B, D	PF18671	4-Hydroxyphenylacetate decarboxylase subunit gamma N-terminal (4HPAD_g_N)	4-Hydroxyphenylacetate decarboxylase subunit gamma N-terminal	4-Hydroxyphenylacetate decarboxylase (4-HPAD) is a heterotetramer consisting of catalytic beta-subunit harboring the putative glycyl/thiyl dyad and a distinct small gamma-subunit with two [4Fe-4S] clusters (EC:4.1.1.83).

The gamma-subunit is proposed to be involved in the regulation of the oligomeric state and catalytic activity of the enzyme and it comprises two domains with some amino acid sequence identity that are structurally related by a pseudo-2-fold symmetry indicating a gene duplication origin. This entry represents the N-terminal domain which binds one [4Fe-4S] cluster through His3, Cys6, Cys19, and Cys36 [1].	Domain

This is a C-terminal domain found in 4-hydroxyphenylacetate decarboxylase small subunit (EC:4.1.1.83), which catalyzes the last reaction in the fermentative production of p-cresol from tyrosine. The C-terminal domain [4F-4S] cluster bears structural similarity to high-potential iron-sulfur proteins (HiPIPs). HiPIPs have an N-terminal extension of 20-40 residues, so the structural similarity is limited to their Fe/S cluster-binding scaffold. Furthermore, despite of the weak amino acid sequence identity, the cluster binding motifs are remarkably similar to H/CX2CX12-13CX16-17C for the gamma-subunit and CX2CX13-19CX14-19C for HiPIPs [1].
