Chemical reactions play important roles in biological functions. In order to elucidate molecular mechanism of the chemical reactions in biosystems, so-called hybrid quantum mechanical/molecular mechanical (QM/MM) methods have been developed and applied to many biochemical reactions recently. The methods permit one to calculate electronic states of reaction substrate molecules in protein binding pockets by taking into account molecular interactions with the surrounding protein environment. In this review, we survey our QM/MM studies for chemical reactions in rhodopsin photoreceptor proteins and F1-ATP synthase along with a brief introduction of the methodology.

Plant heme oxygenase (HO), which catalyzes conversion of heme to biliverdin, being further converted to photo-receptive phycobilins, had been known only in the cell extracts of primitive red algae and cyanobacteria for these twenty years. Recent development of gene analysis, however, has shown that HO is ubiquitously contained in variety of living species. We have succeeded for the first time in obtaining recombinant HO protein of cyanobacteria and in characterizing the HO protein and its heme complex by spectroscopic analyses. Here, we review the existence, role, and characteristics of cyanobacterial and plant HOs in comparison with those of mammalian and bacterial HOs.
