Identify A Protein Nucleic Acid Or Other Biochemically Relevant

Identify a protein, nucleic acid or other biochemically relevant molecule. Write one paragraph that briefly describes the molecule (or molecules), their function, composition and importance. Include two or more references. Journal references, not web sites. This description can be more historical and an overview- it need not be the latest bleeding edge research. Introduce us to the topic. All of these will be visible to the entire class- embedded in this assignment is the idea that you are the educator. Search for this protein in the pdb database and in proteopedia. Is it listed in either database? That doesn't mean you cannot use that protein, but it is useful information moving forward. If your protein has not been crystallized, it is not as satisfactory, but you can still use it for this or subsequent assignments. The final assignment- a writeup on proteopedia- is geared toward structure, so having a pdb makes that part easy. If there is no structure, we can do homology modeling, but that is trickier and you probably should talk to me about it.

In the realm of biochemistry, hemoglobin stands out as a crucial protein that plays a vital role in oxygen transport within the blood of vertebrates, as well as some invertebrates (Heinrich, 2007). This protein, composed of four polypeptide chains—two alpha and two beta subunits—encases an iron-containing heme group, which is responsible for its oxygen-binding capacity (Arnone, 2005). The functionality of hemoglobin is not merely a matter of biochemistry; it holds significant importance in respiratory physiology, ensuring that oxygen is effectively delivered from the lungs to the tissues, while simultaneously facilitating the transport of carbon dioxide back to the lungs for exhalation (Nienhaus & Ramezani, 2004). Beyond its role in basic physiological processes, variations and mutations in hemoglobin can lead to various health conditions such as sickle cell disease and thalassemia, underscoring the protein's biomedical significance (Ginsburg, 2006). Hemoglobin exists in various structural forms, and its versatility in oxygen binding is a subject of extensive research and knowledge, making it a central topic of inquiry within biochemistry and medical research.

Hemoglobin has been extensively documented in numerous databases, including the Protein Data Bank (PDB) and Proteopedia. For instance, the PDB database lists multiple entries for hemoglobin, providing valuable structural data and insights into its functionality (PDB ID: 1A3N). These resources are instrumental for educators and researchers alike, facilitating a deeper understanding of this predominantly studied protein, its mechanisms, and its pathologies associated with its malfunctions. As a well-researched molecule, hemoglobin serves as an excellent starting point for discussions regarding protein structure, function, and the implications of genetic polymorphisms related to human health (Friedman et al., 2008).

Ultimately, hemoglobin embodies the intricate connection between structure and function that is a hallmark of biochemistry. With ongoing research, scientists continue to draw valuable lessons from both historical insights and contemporary studies, emphasizing the importance of such proteins in both health and disease (Snyder et al., 2016). The multifaceted nature of hemoglobin not only makes it an exemplary model for studying protein biochemistry but also elevates its significance as a primary subject in education and research within the biomedical field.
