Here, the first crystal structure of L-proline trans-hydroxylase and its complexes with substrate and product are reported, which reveal the structural basis of trans-cis proline hydroxylation selectivity. Structure comparison with other AKG-dependent hydroxylases identifies conserved amino acid residues, which may serve as signatures of in-line or off-line AKG binding modes in the AKG-dependent enzyme family. Structures of L-proline trans-hydroxylase reveal the catalytic specificity and provide deeper insight into AKG-dependent hydroxylation.,Hu X, Huang X, Liu J, Zheng P, Gong W, Yang L Acta Crystallogr D Struct Biol. 2023 Apr 1;79(Pt 4):318-325. doi: , 10.1107/S2059798323001936.
