Also known as
ECK3063; oat; pat; ygjG
Summary
PatA(YgjG) and Prr(YdcW) form an alternative to the Puu pathway converting putrescine to gamma-aminobutyric acid (Samsonova, 2005). [More information is available at EcoGene: EG12718]. Putrescine transaminase catalyzes the first step in the putrescine degradative pathway, whereby putrescine is converted into 4-aminobutyrate via 4-aminobutyraldehyde . [More information is available at EcoCyc: G7596].

What's a GeneRIF?
  1. rpoS is required for putrescine-dependent ygjG-lacZ expression, but the effect of putrescine on this expression is not caused by simple modulation of RpoS synthesis

  2. crystal belonged to the primitive orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 121.1, b = 129.5, c = 131.3 A, and is estimated to contain four molecules of YgjG per asymmetric unit
