A	PF07503	HypF finger (zf-HYPF)	HypF finger	The HypF family of proteins are involved in the maturation and regulation of hydrogenase ([1]). In the N-terminus they appear to have two Zinc finger domains, as modelled by this family.	Domain
A	PF17788	HypF Kae1-like domain (HypF_C)	HypF Kae1-like domain	This domain is found in the HypF protein. In the structure it is one of the two subdomains of the Kae1 domain [1].	Domain
