Cold-induced aldimine bond cleavage by Tris in Bacillus subtilis alanine racemase.
Bernardo-García N, Sánchez-Murcia PA, Espaillat A, Martínez-Caballero S, Cava F, Hermoso JA, Gago F. Bernardo-García N, et al. Org Biomol Chem. 2019 Apr 24;17(17):4350-4358. doi: 10.1039/c9ob00223e. Org Biomol Chem. 2019. PMID: 30977502
Most of PLP-catalysed reactions, such as those of alanine racemases (AlaRs), present a common resting state in which the PLP is covalently bound to an active-site lysine to form an internal aldimine. The crystal structure of BsAlaR grown in the presence of Tris lacks this …
