Circular dichroism spectra of cleavage fragments of soybean trypsin-chymotrypsin inhibitor

International Journal of Peptide and Protein Research
Y BirkT A Bewley


Circular dichroism spectra of biologically active fragments of Bowman-Birk soybean inhibitor have been determined in acidic, neutral, and alkaline conditions. Neither fragment showed evidence of alpha-helix or beta-structure. Negative dichroism above 260nm has been assigned in both fragments primarily to disulfide bonds, with a minor contribution from tyrosine in a hydrophilic environment. The individual spectra of these fragments, and their sum between 230 and 340 nm have been compared with the spectra of the intact inhibitor and several structurally related proteins. Possible interactions which may give rise to CD bands in this region are discussed.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
