Biochemistry The Polypeptide Chain Configuration in Hemoglobin and other Globular Proteins

By Linus Pauling and Robert B. Corey (1951)

The article named above describes a continuation in the study of hydrogenbonded planar-amide configurations of polypeptide chains. It also discusses evidence on the possibility of the existence of such chains in fibrous proteins, and in molecules of globular proteins.

The article first notes that globular patterns such as ovalbumin, can "on denaturation be converted into a form showing the B-keratin x-ray pattern." Because of such reactions, there is an observance of the fiber axis distance, which is the same as that of ft keratin, which...

For this reason as well, the authors here claim that the same structure (observed above) should be represented by denatured proteins, with some modifications, which they claim is quite an important discovery.
Significant data on this subject is subsequently discussed, especially that relating to the structure of globular proteins, such as those found in carbonmonoxyhemoglobin. The reason this data is mentioned is to provide support for the above theory, namely and specifically to "provide some support for the idea that the 3.7-residue helix is a principal feature of the structure of the protein."

The authors also…

123). In this study, Martinez-Contreras and her associates report the results of recent research that has provided additional evidence concerning the function of these proteins in precursor-messenger RNA (pre-mRNA) splicing (2007). The splicing repression can function in two discrete ways in heterogeneous nuclear RNP proteins; the first way is by antagonizing the recognition of splice sites directly and the second way is through interference with the binding of proteins that

Biochemistry Similarity of Glycolysis in Prokaryotes and Eukaryotes Glycolysis is reported as being a pathway that is practically universal for energy extraction that carbohydrates hold available and this is true for eukaryotes, prokaryotes as well as aerobes and anaerobes. (Essential Biochemistry, 2014, paraphrased) Only eukaryotes have mitochondria. Some prokaryotes are reported to be photosynthetic and to use "an electron transport chain to make ATP."

Altogether, the Icelandic findings implicate epigenetic silencing of the BRCA1 gene in sporadic breast tumors. They even suggest that "the BRCA1 gene is implicated in sporadic breast tumorigenesis through epigenetic silencing and deletion of the BRCA1 gene," and that BRCA1 methylation is also found to be important in hereditary breast cancer, indicating similarities between BRCA1 methylated and hereditary BRCA1 breast tumors (Birgisdotter, et al. 9). While heredity factors strongly contribute
