Fig. 6From: Reconstruction of a Genome Scale Metabolic Model of the polyhydroxybutyrate producing methanotroph Methylocystis parvus OBBPMultiple alignments showing the metallic catalytic sites of pMMO. The dinuclear copper site formed by three histidine residues in subunit B is highlighted in red. The zinc site, formed by two histidine and one aspartic acid residue in subunit C, is highlighted in blue. The mononuclear cooper site, formed by a histidine and an asparagine residue in subunit B, is highlighted in green. In the subunit B3, present in M. hirsuta, asparagine was changed into glutathioneBack to article page
