Fig. 3: Crystal structures of AvmM.

a Cartoon representations of the homotrimeric AvmM. b Close-up active-site view of co-crystal structure of the AvmM active site with product 2. The hydrogen bonding and π–π stacking interaction are presented by gold dash line and green dash line. c Relative activity of AvmM and its site-specific mutants on enzymatic reactions. n = 3 biologically independent experiments; Data are presented as mean values + /− SD and error bars represent SD (standard deviation).
