R. Michalke et al., BACTERIAL CONSTITUENTS .71. ABSOLUTE-CONFIGURATION OF THE ISOPYOVERDIN CHROMOPHORE, Zeitschrift fur Naturforschung. C, A journal of biosciences, 52(7-8), 1997, pp. 549-550
By ozonolytic degradation of the chromophore of isopyoverdin from Pseu
domonas putida BTP 1 L-2,4-diaminobutyric acid was obtained. This prov
