Popis: | Protein patterns from mycelial extracts of Streptomyces griseus strains No. 45H and No. 52-1 were studied by one dimensional gradient PAGE with 20 cm run. The results are reproducible, the protein patterns are the same for the same developmental stage in a given strain. There are well-defined characteristic changes of the protein patterns during the life cycle. The proteins of spores show conspicuous differences compared to protein patterns of the old (72 h) mycelia in the same culture. There is no difference between protein patterns of spores from submerged and from solid media. The protein patterns of two closely related Streptomyces griseus strains significantly differ from each other. After pulse labelling with (14C)-labelled protein hydrolyzate for 40 min, the specific activities of the proteins show considerable differences. There are characteristic bands with low specific activity and others with high incorporation. The fluorograms of the 16, 40 and 64 h cultures show that different proteins are being synthesized intensively at different ages of the culture. |
