Differential in vitro methylation and synthesis of the 480-kilodalton corrinoid protein in Methanosarcina barkeri grown on different substrates.

摘要

The 480-kDa corrinoid protein was significantly methylated in extracts of acetate- but not methanol-grown cells incubated with 14CH3OH, in part because of its decreased synthesis in cells grown on substrates other than acetate. In addition, a 200-kDa corrinoid protein was methylated in extracts of methanol- but not acetate-grown cells.
