Plant acetyl-coa carboxylase polypeptide and gene.

摘要

A purified, biotin-containing polypeptide with a molecular weight of about 50 kilodaltons is disclosed herein. The polypeptide is a subunit of plant acetyl-CoA carboxylase, which catalyzes the carboxylation of plant acetyl-CoA to form plant malonyl-CoA. Modified polypeptides are also disclosed herein as well as methods for obtaining the polypeptides. Also disclosed herein are DNA sequences coding for the polypeptides and methods of obtaining a preferred cDNA sequence by screening a cDNA expression library with antibodies to the 50kD polypeptide.
