Protein Structure
UniProt Annotation
Function Post-translational modification of specific protein by attachment of biotin. Acts on various carboxylases such as acetyl- CoA-carboxylase, pyruvate carboxylase, propionyl CoA carboxylase, and 3-methylcrotonyl CoA carboxylase.
Subcellular Localization Cytoplasm. Mitochondrion.
Disease Associations Holocarboxylase synthetase deficiency (HLCS deficiency) [MIM:253270]: A neonatal form of multiple carboxylase deficiency, an autosomal recessive disorder of biotin metabolism, characterized by ketoacidosis, hyperammonemia, excretion of abnormal organic acid metabolites, and dermatitis. In holocarboxylase synthetase deficiency, clinical and biochemical symptoms improve dramatically with administration of biotin. {ECO:0000269PubMed:10190325, ECO:0000269PubMed:10590022, ECO:0000269PubMed:11735028, ECO:0000269PubMed:12124727, ECO:0000269PubMed:12633764, ECO:0000269PubMed:16134170, ECO:0000269PubMed:7842009, ECO:0000269PubMed:8541348, ECO:0000269PubMed:8817339, ECO:0000269PubMed:9396568}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Mostly expressed in muscle, placenta, in lesser extent in the brain, kidney, pancreas, liver and lung.
