Accession | GenProp0961 |
Name | heme metabolism pair HutWX |
Type | SYSTEM |
Description | The hutW and hutX genes are found in Vibrio cholerae next to hutZ, which is essential for heme utilization. HutW is homologous to the heme carrier protein HemS, while HutW is homologous to (but does not complement) the heme biosynthesis protein HemN. The gene pair is occasionally fused, and may perform a salvage-like function, converting one form of heme into another. HutZ, which resembles the PPOX class heme oxidase HugZ, accompanies roughly half of the occurrences of HutW and HutX. |
