Abstract
Holocarboxylase synthetase (HCS) plays an essential role in biotin utilization in eukaryotic cells and its deficiency causes biotin-responsive multiple carboxylase deficiency in humans. We have cloned the human HCS cDNA and show that antiserum against the recombinant protein immunoprecipitates human HCS. A one base deletion resulting in a premature termination and a missense mutation (Leu to Pro) were found in cells from siblings with HCS deficiency. Human HCS shows homology to BirA, which acts as both a biotin-[acetyl-CoA-carboxylase] ligase and a biotin repressor in E. coli, suggesting a functional relationship between the two proteins. The human HCS gene maps to chromosome 21q22.1.Entities:
