Abstract
Cells of Methanobacterium thermoautotrophicum were fixed with glutaraldehyde, sectioned and labeled with antibodies against the β subunit of component C (=methyl-CoM reductase) of methyl-CoM reductase system and with colloidal gold-labeled protein A. It was found that the gold particles were located predominantly in the vicinity of the cytoplasmic membrane, when the cells were grown under conditions where methyl-CoM reductase was not overproduced. This finding confirms the recent data obtained with Methanococcus voltae showing via the same immunocytochemical localization technique that in this organism methyl-CoM reductase is membrane associated.
