Covalent modifications of histones are a crucial component of epigenetic events that regulate chromatin structures and gene function. Evidence exists that distinct lysine residues in histones are modified by covalent attachment of the vitamin biotin, catalyzed by biotinidase and holocarboxylase synthetase. Biotinylation of histones appears to be conserved across species. The following biotinyla...
Valproic acid (VPA) is a widely used and well-tolerable antiepileptic drug in epileptic patients. However, VPA has many side effects dose-dependent or non-dose-dependent. It is reported that VPA treatment may lead to biotin deficiency and low serum and liver tissue biotinidase enzyme activity (BEA). Major clinical manifestations in biotin deficiency are seborrheic dermatitis, dry skin, fine and...
Multiple carboxylase deficiency is a clinical condition caused by defects in the enzymes involved in biotin metabolism, holocarboxylase synthetase (HLCS) or biotinidase. HLCS deficiency is a potentially fatal condition if left untreated, although the majority of patients respond to oral supplementation of 10-20 mg/day of biotin. Patients who display incomplete responsiveness to this therapy hav...
