Updated annotation (from data): gamma-glutamyl-gamma-aminobutyraldehyde dehydrogenase (EC 1.2.1.99); 4-guanidinobutyraldehyde dehydrogenase (EC 1.2.1.54) Rationale: Specifically important for putrescine utilization as part of the gamma-glutamylputrescine pathway. Similar to the 4-guanidinobutyraldehyde dehydrogenase from P. putida (kauB), which is involved in arginine catabolism, and 92% identical to AO356_12580, which is also involved in arginine catabolism. Mutants in PS417_27745 seem to have a very subtle defect in arginine catabolism; it probably has both activities. Original annotation: aldehyde dehydrogenase Type 1: Protein-coding gene Located on scaffold CP007637, - strand, nucleotides 5,984,320 to 5,985,813 See nucleotide sequence around PS417_27745 or for all of scaffold CP007637
