Abstract
Oxygen molecules have a great impact on protein evolution We have performed a comparative study of key photosynthetic proteins in order to seek the answer to the question did the evolutionary substitution of oxygen and nitrogencontaining residues in the photosynthetic proteins correspond to nutrient constraints and metabolic optimization The D1 peptide in RC II complexes has higher oxygencontaining amino acid residues and PufL/PufM have lower oxygen content in their peptides In this article we also discuss the possible influences of microenvironment and the available nutrients on the protein structure and their atomic distribution
