– Carries out three functions: biotin carboxyl carrier protein, biotin carboxylase and carboxyltransferase. Involved in the synthesis of very-long-chain fatty acid synthesis which is required to maintain a functional nuclear envelope. Required for acylation and vacuolar membrane association of VAC8 which is necessary to maintain a normal morphology of the vacuole. ACC1 Protein, S. cerevisiae, Recombinant (aa 2-581, His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 69.9 kDa and the accession number is Q00955.
