✦ Synopsis

Phosphoglucose isomerase negative mutant of mucoid Pseudomonas aeruginosa accumulated relatively higher concentration of fructose 1,6-bisphosphate (Fru-l,6-Pz) when mannitol induced cells were incubated with this sugar alcohol. Also the toluene-treated cells of fructose 1,6bisphosphate aldolase negative mutant of this organism produced Fru-l,6-P2 from fructose 6-phosphate in presence of ATP, but not from 6-phosphogluconate. The results together suggested the presence of an ATP-dependent fructose 6phosphate kinase (EC 2.7.1.11) in mucoid P. aeruginosa.

## Abstract Treatment of the Class II fructose‐1,6‐bisphosphate aldolase of __Escherichia coli__ with the arginine‐specific α‐dicarbonyl reagents, butanedione or phenylglyoxal, results in inactivation of the enzyme. The enzyme is protected from inactivation by the substrate, fructose 1,6‐bisphospha
