描述
Nigrin b, also known as rufocromomycin or nigrin, is a member of the class of compounds known as bipyridines and oligopyridines. Bipyridines and oligopyridines are organic compounds containing two pyridine rings linked to each other. Nigrin b is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Nigrin b can be found in black elderberry, which makes nigrin b a potential biomarker for the consumption of this food product. rRNA N-glycosylase (EC 3.2.2.22, ribosomal ribonucleate N-glycosidase, nigrin b, RNA N-glycosidase, rRNA N-glycosidase, ricin, momorcochin-S, Mirabilis antiviral protein, gelonin, saporins) is an enzyme with systematic name rRNA N-glycohydrolase. This enzyme catalyses the following chemical reaction Hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from eukaryotic ribosomes .
