Pseudomonas aeruginosa PAO1, PA1421 (gbuA)

Annotation Updates

Date	Description	Acknowledgements
May 1, 2002	Annotation of gene previously described as a agmatinase, with a gene name of speB2. New protein name: guanidinobutyrase. New gene name: gbuA.	Yoshifumi Itoh, Applied Microbiology, National Food Research Institute, Japan
Jul 19, 2002	New genomic context: Transcription start site of an inducible promoter is located 40 bp upstream from the initiation codon of gbuA; GbuR is a LysR-type of transcription activator and it participates in regulation of gbuA. New structure feature: Arginase/agmatinase family of C-N hydrolases; homotetramer of 140 kDa. New evidence reference (PubMed ID): 12029055. Change approved by evidence reference author Yoshifumi Itoh, Applied Microbiology, National Food Research Institute, Japan.	Raymond C. Lo and Fiona S.L.
