Repression in Streptomyces coelicolor
A glucose kinase (glkA) mutant of Streptomyces coelicolor A3(2) M145 was selected by the ability to grow in the presence of the nonmetabolizable glucose analog 2-deoxyglucose. In this glk4 mutant, carbon catabolite repression of glycerol kinase and agarase was relieved on several carbon sources tested, even though most of these carbon sources are not metabolized via glucose kinase. This suggest...

متن کاملReciprocal Crosses in Streptomyces Coelicolor.
interaction of two complementary growth-factor dependent mutants, i.e., Tzp lemen ta ry auxotrophs, of Streptomyces coeticolor to form grovvth-factor independent progeny, i.e., prototrophs, was interpreted as gene recombination by SERMO~TI and SPADA-SERMONTI (1955) and by BRAENDLE and SZ+BALSKI (1959yi but as heterokaryosis by BRADLEY (1957). The former workers concluded that gene recombination...
متن کاملGene recombination in Streptomyces coelicolor.
Prototrophic recombinant strains were obtained by plating on minimal medium spores from mixed cultures grown on limiting agar, of two strains each with a different double nutritional requirement. Clones showing new associations of properties were isolated on partially supplemented media. Some showed one ‘ mutant ’ character derived from one of the starting strains and ‘wild’ characters derived ...
متن کاملStructure-Dependent Interfacial Properties of Chaplin F from Streptomyces coelicolor
Chaplin F (Chp F) is a secreted surface-active peptide involved in the aerial growth of Streptomyces. While Chp E demonstrates a pH-responsive surface activity, the relationship between Chp F structure, function and the effect of solution pH is unknown. Chp F peptides were found to self-assemble into amyloid fibrils at acidic pH (3.0 or the isoelectric point (pI) of 4.2), with ~99% of peptides ...
