Bio-Engineering: Making and Testing Model Proteins
Read the Fine Print
Educational Use
Rating
0.0 stars

Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child’s body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges posed by the R&D; bio-engineering hypothetical scenario. Using common classroom supplies such as paper, tape and craft sticks, student pairs design, sketch, build, test and improve their own protein models to meet specific functional requirements: to strengthen bones (collagen), to capture oxygen molecules (hemoglobin) and to capture bacteria (antibody). By designing and testing physical models to accomplish certain functional requirements, students come to understand the relationship between protein structure and function. They graph and analyze the class data, then share and compare results across all teams to determine which models were the most successful. Includes a quiz, three worksheets and a reference sheet.

We are happy to welcome you to our second Open Educational Resource (OER) textbook, Biochemistry Free For All. Biochemistry is a relatively young science, but its rate of growth has been truly impressive. The rapid pace of discoveries, which shows no sign of slowing, is reflected in the steady increase in the size of biochemistry textbooks. Growing faster than the size of biochemistry books have been the skyrocketing costs of higher education and the even faster rising costs of college textbooks. These unfortunate realities have created a situation where the costs of going to college are beyond the means of increasing numbers of students.

The video's transcript is also provided in full, with a portion provided below for preview:

"The skin micro-environment varies across the body. But one thing that remains constant is the presence of microorganisms that affect skin health. In a recent study, researchers gathered more than 800 organisms from 3 body sites of 17 individuals. Analyses revealed 30+ bacterial genera and 14+ fungal genera, with the most prevalent being Staphylococcus and Micrococcus bacteria. Further tests showed that the collected microbes had the capacity to break down a variety of compounds. including amino acids, steroids, lipids, and sugars, as well as compounds derived from personal care products. This collection of micro-organisms represents a valuable resource for skin microbiome research, with the potential for developing novel therapeutics and for gaining insight into the metabolic activities of the skin microbiota..."

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Notch signaling is the key to many binary decisions metazoan cells make during development. Downstream signals from Notch trigger transcriptional remodeling that resolves dichotomies like differentiation between developmental cell fates. In the "Notch on" state, the Notch intracellular domain (NICD) relocates to the nucleus and binds to the protein RBPJ. While Notch activation is well studied, the transition to the "Notch off" state, where NICD and RBPJ dissociate, is not well understood. Recent research using phylogenetic analysis, computational biochemistry, and in vitro experiments suggests that heat flux is an important regulator of Notch signaling. The researchers determined that NICD senses temperature changes through its ankyrin domain. The ankyrin domain is highly conserved across species and contains β-hairpins enriched for charged amino acids. These charged amino acids amplify destabilizing electrostatic interactions, making the domain vulnerable to heat destruction..."

The Online Macromolecular Museum
Rating
0.0 stars

The Online Macromolecular Museum (OMM) is a site for the display and study of macromolecules. Macromolecular structures, as discovered by crystallographic or NMR methods, are scientific objects in much the same sense as fossil bones or dried specimens: they can be archived, studied, and displayed in aesthetically pleasing, educational exhibits. Hence, a museum seems an appropriate designation for the collection of displays that we are assembling. The OMM's exhibits are interactive tutorials on individual molecules in which hypertextual explanations of important biochemical features are linked to illustrative renderings of the molecule at hand.

Why devote a site to detailed visualizations of different macromolecules? In learning about the intricacies of life processes at the molecular level, it is important to understand how natural selection has fashioned the structure and chemistry of macromolecular machines to suit them for particular functions. This understanding is greatly facilitated by the visualization of 3-dimensional structure, when known. So, if static views of molecules (even in stereo) are worth a thousand words, then interactive animations of molecules should be worth much more. Indeed, we have found the types of displays represented here invaluable in gaining an appreciation for the details of key biochemical processes.

As Carl Brandon and John Tooze stated in their classic text, Introduction to Protein Structure:
"Molecular biology began some 40 years ago with the realization that structure was crucial for a proper understanding of function. Paradoxically, the dazzling achievements of molecular genetics and biochemistry led to the eclipse of structural studies. We believe the wheel has now come full circle, and those very achievements have increased the need for structural analysis at the same time that they have provided the means for it."

It is our opinion that structural analysis should extend into the classroom: as students learn about cellular mechanisms it is important that they study the chemistry of the molecular machines involved. These considerations have motivated the construction of the OMM.

The OMM is part of a collaborative effort by faculty and students interested in macromolecular structure-function relationships. The primary authors of some tutorials are students of David Marcey and he serves as author, co-author and site editor, and assumes all responsibility for content. Any criticisms, suggestions, comments, or questions should be sent to him at: marcey@callutheran.edu. All tutorials are copyrighted.

The OMM was started in 1996 for a Molecular Biology class at Kenyon College, where DM was a professor in the Biology Department (1990-1999). The OMM is now developed and housed at California Lutheran University, where DM has been a professor since 1999.

"The composition of our gut microbial community has been linked directly to our health, but researchers are only beginning to study the impact of its functional metabolic behavior, which can shift in response to external factors. Microbial production of H₂S in the gut is one such function, and it may be a colorectal cancer trigger. A recent study used publicly available datasets to examine the sulfur metabolism genes in our gut microbiota. Sulfur metabolism genes were more abundant and diverse than previously thought and were correlated with colorectal cancer. The researchers also examined two key sulfate reductases: dissimilatory sulfite reductases (Dsr) and anaerobic sulfite reductase (asr) and found that genes for asr were twice as abundant as genes for Dsr, suggesting that asr is a more important contributor to sulfate reduction in the human gut and found that genes for asr were twice as abundant as genes for Dsr, suggesting that asr is a more important contributor to sulfate reduction in the human gut..."
