A coenzyme-F420 non-reducing [NiFe] hydrogenase was isolated from Meth
anococcus voltae. It consists of three subunits. They are the products
of the previously identified genes vhuA, vhuG and vhuU. The vhuU gene
product is of only 25 amino acids. This novel very small hydrogenase
subunit contains selenocysteine within a conserved amino-acid sequence
previously shown to be involved in Ni coordination. The subunit is sh
orter than the predicted primary gene product and is therefore apparen
tly post-translationally processed.
