Metabolite Identification
Common NameBiocytin
DescriptionBiocytin is a naturally occurring low molecular weight analog of biotin, and a primary source of this essential metabolite for mammals. Biotinidase acts as a hydrolase by cleaving biocytin and biotinyl-peptides, thereby liberating biotin for reutilization. Mammals cannot synthesize biotin and, therefore, derive the vitamin from dietary sources or from the endogenous turnover of the carboxylases. Free biotin can readily enter the biotin pool, whereas holocarboxylases or other biotin-containing proteins must first be degraded proteolytically to biocytin (biotinyl-e-lysine) or biotinyl-peptides. Biocytin is also an especially versatile marker for neuroanatomical investigations, shown that may have multiple applications, especially for labeling neurons. (PMID:8930409 , 1384763 , 2479450 ).
