This entry represents the single Cache domain 2 (sCache_2), which contains the long N-terminal helix domain [1]. This domain recognises pyruvate, acetate, propionate, glycolate, L-lactate, acetoacetate, urea and hydroxyurea, acetamide, formamide, L-malate and citromalate, malonate, methyl and bromosuccinate and citraconic acid (Matilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).
