Crystal structure of the R54G mutant of putrescine transcarbamylase from Enterococcus faecalis bound to a curing guanidinium ion

Function

[PTC_ENTFA] Catalyzes the phosphorolysis of N-carbamoylputrescine to form carbamoyl phosphate and putrescine. Is involved in the degradation pathway of the polyamine agmatine. Also has weak activity with ornithine and cadaverine.^[1]

About this Structure

4am8 is a 6 chain structure with sequence from Enterococcus faecalis. Full crystallographic information is available from OCA.
