RACo linker region This family includes reductive activator of CoFeSP (RACo) proteins. Structure analysis of RACo indicate that it contains 4 regions: N-terminal region pfam00111 (residues 3-94) binding the [2Fe-2S] cluster, a linker region (residues 95-125), the middle region (residues 126-206), and the large C-terminal domain pfam14574 (residues 207-630). This entry pertains to the linker region. The linker region is only present in RACE (reductive activases for corrinoid enzymes) protein sequences with the N-terminal [2Fe-2S] cluster family pfam00111 and is absent in the RamA-like RACE proteins, suggesting that the linker domain and the N-terminal domain form one functional unit. |
