Fig. 1. Schematic representation of a putative pathway producing putrescine from glutamate in S. putrefaciens strains 200 and CN-32. Substrates and products are indicated.
Putative enzyme EC numbers deduced from genome annotation available in public databases are provided. Gray or dashed arrows indicate enzymes for which a putative encoding
gene is present in only one of the two strains whose genome has been sequenced.
