From: Uncovering a superfamily of nickel-dependent hydroxyacid racemases and epimerases
(a) NPN cofactor and catalytic mechanism of LarA. (b) Substrates identified in the LarA superfamily in Fisher projection. Only one substrate is shown for each pair of substrates, except for G2E. The green asterisks show the sites of stereoinversion, the black asterisks indicate other stereocenters in the molecule.
