Garg et al. determined structures of human Fructosamine-3-kinase (FN3K) bound with different nucleotide analogues and a small molecule sugar mimic substrate. Accompanied by biochemical analysis, they revealed features of the enzyme important for kinase activity and sugar moiety dynamics, providing mechanistic insights into FN3K function.
