Methylene-H4MPT reductase

Methylene-H4MPT is reduced by p42o-dependent methylene-H4MPT reductase to methyl-H4MPT [ 115,116,189,190,193] ... [Pg.53]

All methylene-H4MPT reductases purified are air stable, to some extent [54,115,116,... [Pg.83]

Methylene-H4MPT reductase Methanobacterium ther- 150 (36) none H2F420 0.30 6000 3600 54,116... [Pg.84]

Reduction of 7/, A °-methylene-H4MPT to A( -methyl-H4MPT is catalyzed by methylene-H4MPT reductase (Reaction 5, Table 2). Reduced coenzyme factor F420 is the physiological electron donor. The enzyme appears to be soluble and not to contain a prosthetic group [67-69a]. The subsequent methyl-group transfer from... [Pg.123]

Methyl-H MPT coenzymeM methyltransferase - coupled to primary Na translocation. Methylene-H4MPT conversion to methyl-CoM involves two reactions (Table 2) methylene-H4MPT reductase (Reaction 5) and CFl3-H4MPT H-S-CoM methyltransferase (Reaction 6). [Pg.133]

Methylene-H4MPT reductase catalyzes the reduction of methylene-H4MPT to methyl-H4MPT with factor F420 as the physiological electron donor ... [Pg.133]

Fig. 6. Proposed mechanism of the generation of a primary electrochemical sodium potential (AftNa ) coupled to methylene-HaMPT (CH2=H4MPT) conversion to methyl-coenzyme M (CH3-S-C0M) Methyl-H4MPT coenzymeM (H-S-CoM) methyltransferase as a primary Na pump. Numbers in circles (1) methylene-H4MPT reductase (2) CH3-H4MPT H-S-CoM methyltransferase the hatched box indicates membrane-bound methyltransferase n is an unknown stoichiometric factor. Fig. 6.
