A novel hydrogenase has recently been found in methanogenic archaea. It catalyzes the reversible dehydrogenation of methylenetetrahydro-methanopterin (CH sub(2) = H sub(4) MPT) to methenyltetrahydro-methanopterin (CH identical with H sub(4)MPT super(+)) and H sub(2) and was therefore named H sub(2)-...
