摘要
The Escherichia coli open reading frame f413, which has the potential to code for a polypeptide homologous to cardiolipin (CL) synthase. has been cloned. Its polypeptide product has a molecular mass of 48 kDa, is membrane-bound, and catalyzes CL formation but does not hydrolyze CL. A comparison of the sequences predicted for the polypeptides encoded by f413 and cls indicates that the N-terminal residues specified by cls may be unnecessary for CL synthase activity. Construction of a truncated cls gene and characterization of its polypeptide product have confirmed this conclusion. (C) 2000 Elsevier Science B.V. All rights reserved.
