Holocarboxylase synthetase is one of two enzymes known to be involved in the metabolism of biotin. It catalyses the fixation of biotin to inactive apocarboxylases yielding active carboxylases. Deficiency of this enzyme leads to multiple carboxylase deficiency which is fatal in the absence of prompt
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 supplementat
