ID MCRB$METTH STANDARD; PRT; 426 AA. AC P11560; DT 01-OCT-1989 (REL. 12, CREATED) DT 01-OCT-1989 (REL. 12, LAST SEQUENCE UPDATE) DT 01-OCT-1989 (REL. 12, LAST ANNOTATION UPDATE) DE METHYL COENZYME M REDUCTASE COMPONENT C BETA SUBUNIT (GENE NAME: DE MCRB). OS METHANOBACTERIUM THERMOAUTOTROPHICUM. OC PROKARYOTA; ARCHAEBACTERIA; METHANOGENS. RN [1] (STRAIN MARBURG, SEQUENCE FROM N.A.) RA BOKRANZ M., BAEUMNER G., ALLMANSBERGER R., ANKEL-FUCHS D., KLEIN A.; RL J. BACTERIOL. 170:568-577(1988). CC -!- FUNCTION: THIS ENZYME COMPLEX CATALYZES THE FINAL STEP IN CC METHANOGENESIS, WHICH IS THE TERMINAL STEP OF ANAEROBIC CC DEGRADATION OF BIOMASS. CC -!- CATALYTIC ACTIVITY: REDUCTION OF CH(3) MOIETY OF 2-(METHYLTHIO) CC ETHANESULFONIC ACID, RESULTING IN THE RELEASE OF METHANE. CC -!- THIS COMPLEX ENZYME HAS BEEN RESOLVED BY PURIFICATION INTO CC PROTEIN COMPONENTS A AND C AND A SMALL COFACTOR, COMPONENT B. CC COMPONENT C IS THOUGHT TO BE THE ACTUAL SITE OF METHYL GROUP CC REDUCTION. CC -!- SUBUNIT: COMPONENT C IS COMPOSED OF THREE SUBUNITS: ALPHA, BETA, CC AND GAMMA.
