Amino-acid binding pocket of PvSHMT. (a) D-Ser in the ternary complex PvSHMT–D-Ser–5FTHF with the PLP–D-Ser (PLD) Schiff base and (6R)-5FTHF coloured in magenta in protomer A (pink) and protomer B (blue) with a glycerol (GOL) molecule in green. (b) L-Ser in the binary complex PvSHMT–L-Ser with a PLP–L-Ser (PLS) Schiff base. (c) Superposition of the two complexes showing the configurations of D-Ser and L-Ser. |
