This domain is found at the C-terminal end of Carbamoyltransferase from Caldanaerobacter subterraneus (HypF, Swiss:Q8RDB0) and similar prokaryotic sequences. HypF is involved in the biosynthesis of the nitrile group as a precursor of the cyano groups of hydrogenases. HypF consists of four domains: the acylphosphatase domain (Pfam:PF00708), the Zn finger-like domain (Pfam:PF07503), the YrdC-like domain (Pfam:PF01300) and the Kae1 (kinase-associated endopeptidase 1)-like domain, which is composed of two alpha-beta subdomains (Pfam:PF17788 and this entry) [5].	Domain
A, B	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
