Updated annotation (from data): gamma-glutamyl-gamma-aminobutyrate hydrolase (EC: 3.5.1.94) Rationale: Specifically important in nitrogen source Putrescine Dihydrochloride; nitrogen source Propandiamine. 38% identical to E. coli PuuD. This reaction is the next step of putrescine degradation after gamma-glutamyl-putrescine ligase (PP_5184) and oxidase (PP_2448). The phenotype on propandiamine suggests that it is also active on 3-glutamyl-3-aminopropionate.
