We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here. During the move, Proteopedia will be read only for a short time.
Pseudomonas putida PqqB with a non-physiological zinc at the active site binds the substrate mimic, 5-cysteinyl-3,4-dihydroxyphenylalanine (5-Cys-DOPA), non-specifically but supports the proposed function of the enzyme in pyrroloquinoline quinone biosynthesis.
6e13 is a 1 chain structure with sequence from Pseudomonas putida KT2440. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
