Methyl CoM reductase (MCR;Coenzyme-B sulfoethylthiotransferase) (EC 2.8.4.1)
: all
biologically generated methane on earth derives from the catalytic activity of MCR in
methanogenic microbes. It also appears to catalyze anaerobic methane oxidation. MCR
catalyzes the conversion of methylcoenzyme M (methyl-SCoM) and N-7- mercaptohep-
tanoylthreonine phosphate (CoBSH) to methane and the CoB-SS-CoM heterodisulide
(Ragsdale
2003
; Jaun and Thauer
2007
).

Carbon monoxide (CO) dehydrogenase (EC 1.2.99.2)
: catalyzes the reversible oxidation of
CO to CO
2
, allowing anaerobic microbes to grow with CO or CO
2
as their sole carbon
source and with CO as the only energy supply (Lindahl and Graham
2007
)

Acetyl CoA synthase (EC 6.2.1.1)
: interacts tightly with CODH to form a heterotetrameric (a
2b2) machine that couples to catalyze acetyl-CoA synthesis from CO
2
, a methyl group donated
by the methylated corrinoid iron-sulfur protein (CFeSP), and CoA (Doukov et al.

).

covalent adducts with DNA, to lactate (Sukdeo et al.
