Purity > 85% as determined by SDS-PAGE. MW: 67.6kDa. Partial: 217-775aa. N-terminal 10xHis-tagged. Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). 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.
