COMMENTARY hide
LITERATURE
analysis
examination of protein-membrane interactions between P450scc and its redox partners on 1,2-dimyristoyl-sn-glycero-3-phosphocholine membranes containing cholesterol (20%), using a quartz crystal microbalance with dissipation monitoring
biotechnology
-
the development of a cholesterol biosensor based on screen-printed electrodes modified with multi-walled carbon nanotubes and with the cytochromes P450scc may ensure a high sensitivity. Role of the nanotubes in mediating electron transfer to the cytochrome P450scc is verified as further improved with respect to the case of rhodium-graphite electrodes modified by the use of gold nanoparticles
drug development
-
the vitamin D3 derivatives produced by the action of P450scc are good candidates for use in the therapy of hyperproliferative disorders
medicine
synthesis
construction of a fusion protein consisting of cytochrome P450scc (CYP11A1), adrenodoxin and adrenodoxin reductase including 2A peptide from Picornaviridae which is capable of self-cleavage. Introduction to Escherichia coli leads to a high level of expression but no cleavage. In yeast Saccharomyces cerevisiae, the discrete proteins P450scc-2A, adrenodoxin-2A and adrenodoxin reductase are expressed, with a significant proportion present in a fusion adrenodoxin-2A-adrenodoxin reductase. The enzyme system is catalytically active
