Lactose metabolism in Erwinia chrysanthemi.
Wild-type strains of the phytopathogenic enterobacterium Erwinia chrysanthemi are unable to use lactose as a carbon source for growth although they possess a beta-galactosidase activity. Lactose-fermenting derivatives from some wild types, however, can be obtained spontaneously at a frequency of about 5 X 10(-7). All Lac+ derivatives isolated had acquired a constitutive lactose transport system...
متن کاملLactose and melibiose metabolism in Erwinia chrysanthemi.
A Lac+ mutant of Erwinia chrysanthemi was isolated from the Lac- wild type on lactose agar. beta-Galactosidase was expressed independently of lactose transport in both the mutant and the wild type, and neither strain expressed thiogalactoside transacetylase. Lactose transport and alpha-galactosidase, constitutive in the Lac+ strain, were coordinately induced in the Lac- strain by melibiose and ...
متن کاملCharacterization of the pecT control region from Erwinia chrysanthemi 3937.
Erwinia chrysanthemi synthesizes and secretes pectate lyases that attack components of the plant cell wall and, therefore, play a major role in the pathogenesis of soft rot disease. We isolated a new mutant (designated pec-1), by Tn5 mutagenesis, that displays weak pectate lyase production and decreased motility and mucoidicity. Maceration and pathogenicity tests done on different plant organs ...
متن کاملAtomic resolution structure of Erwinia chrysanthemi L-asparaginase.
An X-ray structure of L-asparaginase from Erwinia chrysanthemi (ErA) has been refined at 1 A resolution to an R factor of below 0.1, using data collected on a synchrotron source. With four molecules of the enzyme consisting of 327 amino acids each, this crystal contains one of the largest asymmetric units of a protein refined to date at atomic resolution. Previously, structures of ErA and of re...
متن کاملGeneralized transduction in the enterobacterial phytopathogen Erwinia chrysanthemi.
Bacteriophages induced by mitomycin treatment of Erwinia chrysanthemi KS612 produced plaques on lawns of E. chrysanthemi EC183 and KS605. Bacteriophage Erch-12, purified from one such plaque, transferred an array of chromosomal genes (arg, leu, his, ser, thr, trp, ura) to appropriate recipient strains derived from E. chrysanthemi EC 183. Recombinants were formed in the absence of cellular conta...
