Structure comparison of the catalytic sites in BL00235 and YwfE. (a) Stereo diagram of the superimposed model structure of the BL00235–PP transition-state analogue complex. The superimposed PP analogue is shown as a ball-and-stick model with C atoms in green. Protein residues surrounding the PP analogue are shown as stick models with C atoms in yellow. Putative interactions are indicated by broken lines coloured light blue. (b) Stereo diagram of the structure of the YwfE–PP transition-state analogue complex. The PP analogue molecule bound to YwfE is shown as a ball-and-stick model with C atoms in green. Protein residues surrounding the PP analogue are shown as stick models with C atoms in yellow. The hydrogen bonds are indicated by broken lines coloured light blue. (c) Surface representation of the substrate-binding pocket of BL00235. An asterisk indicates the N-terminal Cβ atom of the superimposed PP analogue. (d) Surface representation of the substrate-binding pocket of YwfE. An asterisk indicates the N-terminal Cβ atom of the PP analogue bound to YwfE. |
