The maintenance of genomic stability is a fundamental requirement for the normal functioning of cells.8,9,10,11Under normal conditions, cells have developed a series of checkpoints and mechanisms to stringently control the passage of intact and correct genetic information, serving as safeguards that ...
Enzymes lacking coenzymes usually require the formation of ternary complexes. Ordered sequential mechanisms have been attributed to steric hindrance of substrates and/or to changes in protein conformation during catalysis. Extensive literature on specific examples have been the object of several reviews (...
Noticeable examples of genes directly regulated by the GSR among the genes with annotated function are the stress inducible csbD (SGRAN_3063), two katA catalases (SGRAN_1770 and SGRAN_2521)4, the ecnAB toxin-antitoxin system29 (SGRAN_1922), an mscS mechanosensitive ion channel30 (SGRAN_...
Examples of the use of fluorescence line narrowing were discussed [136] in respect of heme proteins, photosynthetic systems and tryptophan-containing proteins. Sign in to download full-size image Fig. 9. Angle dependence of inverse correlation time for (1, 3) monodisperse and (2, 4) poly...
A common problem encountered by synthetic chemists is to carry out a reaction at just one of two similar functional groups in the substrate molecule. Examples include protection/deprotection of just one hydroxyl group in a diol, addition to only one carbonyl of a diketone, etc. The problem, as...
The mitogen-activated protein kinases (MAPKs) are a family of enzymes conserved among eukaryotes that regulate cellular activities in response to numerous ... WF Waas,HH Lo,KN Dalby - 《Journal of Biological Chemistry》 被引量: 123发表: 2001年 Two Coupled Components of the Mitogen-Activated Pr...
Biocatalysts that perform C–H hydroxylation exhibit exceptional substrate specificity and site-selectivity, often through the use of high valent oxidants to activate these inert bonds. Rieske oxygenases are examples of enzymes with the ability to perform precise mono- or dioxygenation reactions on a ...
Data1). These putative CBGs were expressed in at least one tissue, and 26 of them showed much higher expression levels in the fruit placenta than in other tissues (Supplementary Fig.12); therefore, serving as strong candidates for full elucidation of capsaicinoid biosynthetic enzymes. ...
