  ID: BTD_HUMAN
DESCRIPTION: RecName: Full=Biotinidase; Short=Biotinase; EC=3.5.1.12; Flags: Precursor;
FUNCTION: Catalytic release of biotin from biocytin, the product of biotin-dependent carboxylases degradation.
CATALYTIC ACTIVITY: Biotin amide + H(2)O = biotin + NH(3).
SUBCELLULAR LOCATION: Secreted, extracellular space.
DISEASE: Defects in BTD are the cause of biotinidase deficiency (BTD deficiency) [MIM:253260]; also called late-onset multiple carboxylase deficiency. BTD deficiency is a juvenile form of multiple carboxylase deficiency, an autosomal recessive disorder of biotin metabolism, characterized by ketoacidosis, hyperammonemia, excretion of abnormal organic acid metabolites, and dermatitis. BTD deficiency is characterized by seizures, hypotonia, skin rash, alopecia, ataxia, hearing loss, and optic atrophy. If untreated, symptoms usually become progressively worse, and coma and death may occur.
SIMILARITY: Belongs to the CN hydrolase family. BTD/VNN subfamily.
SIMILARITY: Contains 1 CN hydrolase domain.
CAUTION: It is uncertain whether Met-1 or Met-21 is the initiator.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
