✦ Synopsis

The phaseolotoxin-producing Pseudomonas syringae pv. phaseolicola strain 1321 contains two ornithine carbamoyltransferases which differ in resistance to phaseolotoxin. Whereas ornithine carbamoyltransferase 1 (OCT 1 ) is inhibited a t low concentrations of phaseolotoxin. ornithine carbamoyltransferase 2 (OCT 2 ) is insensitive to phaseolotoxin. The activity of the insensitive enzyme is correlated with the amount of toxin formed.

Independently of their capacity to produce phytotoxins. strains of Pseudornonas syringae pv. phaseolicola contain two ornithine carbamoyltransferases (OCT, EC 2.1.3.3.) which differ in resistance to phaseolotoxin and Orn-P(0) (NH&NH-SO, H (PNSOrn). At 18 "C, the optimal temperature for product forma
