Crystal structures of a [NiFe] hydrogenase large subunit HyhL in an immature state in complex with a Ni chaperone HypA [Biochemistry]

Ni-Fe clusters are inserted into the large subunit of [NiFe] hydrogenases by maturation proteins such as the Ni chaperone HypA via an unknown mechanism. We determined crystal structures of an immature large subunit HyhL complexed with HypA from Thermococcus kodakarensis. Structure analysis revealed that the N-terminal region of HyhL extends…
