Biotin

Seizures are reported as resolving in hours to days, with other symptoms resolving within weeks. Biotinidase catalyzes the cleavage of biotin from biocytin and biotinyl-peptides (the proteolytic degradation products of each holocarboxylase) and thereby recycles biotin. 3-Methylcrotonyl-CoA is an intermediate step in the catabolism of the amino acid leucine. Indirect measures depend on the biotin requirement for carboxylases. Low activity of this enzyme causes a failure to recycle biotin from biocytin.
