Comment | Members of this radical SAM protein subfamily, designated NirJ2, occur in genomic contexts with a paralog NirJ1 and with other nitrite reductase operon genes associated with heme d1 biosynthesis, as in Heliobacillus mobilis and Heliophilum fasciatum. NirJ2 is presumed by bioinformatics analysis (Xiong, et al.) to be a heme d1 biosynthesis protein by context. This model has been redone (2014) to remove the branch (TIGR04545) that included DVU_0855, from a similar pathway for heme b biosynthesis. |
