heme
the crystal structure of NP4 reveals a lipocalin-like eight-stranded beta barrel, with heme inserted into one end of the barrel
heme b
nitrophorins bind the heme b cofactor in the beta-barrel of their lipocalin fold, which is further anchored through a proximal histidine-Fe(III) bond. Ferriheme is not reduced by excess NO
heme b
the catalytic NO2 disproportionation is supported by the ferriheme of nitrophorin 4
heme b
the catalytic NO2 disproportionation is supported by the ferriheme of nitrophorin 7
