[Distribution in the genomes of microorganisms of fragments homologous to cDNA of chicken pro-alpha1(1) collagen].

Southern-analysis of genomic DNAs from 14 yeast species (Ascomycetes and Basidiomycetes) with alpha 1(1) chicken collagen cDNA coding for triple-helical domain as a probe, has shown that presence of genomic fragment, homologous to collagen genes of higher eucaryotes, is characteristic for yeasts. In bacterial genomes such fragments are revealed quite rarely. No collagen-like sequences has been found in known yeast proteins by computer-analysis.
