Fig. 4From: Pterostilbene production by microorganisms expressing resveratrol O-methyltransferaseTertiary model of ROMT represented in ribbon form. Substrates are represented by stick model in cyan. Substrate binding residues are represented by stick model in red. F167A, D174A, W258A, H261A (predicted to be key amino acids for activity, with H261 being the most important) were constructed by site-directed mutagenesisBack to article page
