Genomic fragments, homologous to chicken A1(1) collagen cDNA encoding triple-helical domain, were revealed by Southern analysis in various fungi. Such a genomic fragment from Candida utilis was cloned and sequenced. Analysis of the obtained DNA sequence revealed the 119 bp segment, which has possibly originated from the 54 bp module common for the fibrillar collagen genes of higher eukaryotes.

In the cells of hybrid yeast strain Saccharomyces N.C.Y.C. 644 SU3 (Karlsberg collection), a large amount of pyrophosphate (30-300 micro mol per g of dry weight) accumulates whatever the aeration conditions and the contest of glucose in the medium. The content of pyrophosphate is 10-100 times higher than that of ATP. At the early and mid-exponential growth phases two maxima of pyrophosphate accumulation are observable. The periods of maximal pyrophosphate accumulation in yeast coincide with those of the minimal contest of polymeric acid-soluble polyphosphates and intense budding. In the light of the data obtained, the question is discussed as to the relationship between the metabolism of pyrophosphates and acid-soluble polyphosphates in yeats.
