Biotinidase catalyzes the hydrolysis of N epsilon-biotinyllysine (biocytin) to form biotin and free lysine. The enzyme has been purified 4800-fold from outdated human plasma and was determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to have a molecular weight of (76

Posttranslational modification of histones by biotinylation can be catalyzed by both biotinidase (BTD) and holocarboxylase synthetase. Biotinylation of histones is an important epigenetic mechanism to regulate gene expression, DNA repair, and chromatin remodeling. The role of BTD in histone biotinylation

Children with juvenile-onset multiple carboxylase deficiency lack biotinidase activity (biotinamide amidohydrolase, EC 3.5.1.12) in the liver and other tissues. Hence, little free biotin is metabolically available, resulting in seizures, acidosis, and serious neurological damage. As the absence of hepatic biotinidase
