... absorption bands. Heme catabolism byHOs of mammals, pathogenic bacteria, cyanobacteria and probably insects is considered to have a similarmechanism, because the characteristic absorptionbands of verdoheme ... degradation rate of GmHO-1, indi-cated in Table 4, is comparable to that of SynHO-1 inthe presence of NADPH, FNR, and Fd, and also tothat of rHO-1 in the presence of NADPH and CPR.Here, NADPH ... Then, a broad bandappeared at around 660 nm, and was maximal 9–12 minafter initiation of the reaction. The spectral features of the final reaction mixture were analogous, but not iden-tical,...
