Figure 3
YncD possesses a conserved positively charged substrate-binding pocket. (a) A cartoon representation of YncD colored as in Fig. 2(a) (left) and a surface representation in the same orientation showing the substrate-binding pocket (right). (b) A stereoview of the amino acids in the YncD substrate-binding pocket which are conserved in YncD homologues according to ConSurf (Ashkenazy et al., 2016). The region shown corresponds to the boxed region in (a), YncD is shown as a cartoon representation and conserved residues are shown as sticks. (c) A stereoview of positively charged conserved residues in the YncD substrate-binding pocket. (d) An electrostatic surface representation of the substrate-binding pocket of YncD. (e) A surface representation of the YncD substrate-binding pocket with amino acids color-coded according to their level of conservation across YncD homologues as determined by ConSurf (Ashkenazy et al., 2016). The region of YncD shown in (d) and (e) corresponds to the boxed region in (a). |
