Gene Gene information from NCBI Gene database.
Entrez ID 686
Gene name Biotinidase
Gene symbol BTD
Synonyms (NCBI Gene)
-
Chromosome 3
Chromosome location 3p25.1
Summary The protein encoded by this gene functions to recycle protein-bound biotin by cleaving biocytin (biotin-epsilon-lysine), a normal product of carboxylase degradation, resulting in regeneration of free biotin. The encoded protein has also been shown to have
