Structural highlights
Function
PANZ_ECOLI Controls both the activation and catalytic activity of PanD in a coenzyme A (CoA)-dependent fashion. Binding of CoA or a derivative to PanZ leads to interaction with PanD, which promotes the processing and activation of pro-PanD, and subsequent substrate-mediated inhibition of the active form of PanD (PubMed:23170229, PubMed:25910242). Inhibition of PanD activity is probably the primary metabolic role of PanZ, allowing negative feedback regulation of pantothenate biosynthesis by CoA (PubMed:25910242).[1] [2]
