While the substrate specificity is strict for the terminal sugar in the substrate, the enzymes display a broad specificity toward the aglycone and the leaving group in the substrate. In fact, the substrates for the glycosidases that are frequently used in an activity assay are synthetic glycosides...

Human APOBEC3A is a single-stranded DNA cytidine deaminase that restricts viral pathogens and endogenous retrotransposons, and has a role in the innate immune response. Furthermore, its potential to act as a genomic DNA mutator has implications for a rol
substratesin vivo. To do this, we immunoprecipitated ADMA-containing peptides using ADMA antibodies in two parental and CARM1 KO paired cell lines, MCF7 and MDA-MB-231, and mapped the sites of arginine methylation using nano-liquid chromatography tandem mass spectrometry (nanoLC-MS/MS) in ...

Wilfried,Bieger,and,George,Scheele 摘要: A method for the determination of elastase activity is described which uses soluble α-[3H]elastin as substrate. Soluble α-elastin was shown to have the same substrate specificity as natural insoluble elastin. At a substrate concentration of 1 mg/ml, ...
