The synthesis of poly(2-amino-6-chloropurinylic acid) [poly(n2cl6Pu)] by the polynucleotide phosphorylase catalyzed polymerization of 2-amino-6-chloro-9-(beta-D-ribofuranosyl)purine 5'-diphosphate and its chemical conversion to poly(6-thioguanylic acid) [poly(s6G)] is described. Poly(s6G) was found to form a relatively unstable complex with poly(C), the properties of which were incompatible with those previously reported for the same complex prepared by another method [Darlix, J.L., Fromageot, P., and Reich, E. (1973), Biochemistry 12, 914]. It was found that poly(s6G) could be thermally converted to a copolymer of which with poly(C) was strikingly similar to that reported earlier for poly(s6G)-poly(C).
By means of manometric technique the influence of X-ray-repairsubstances on the growth and respiration of Micrococcus denitrificans, Micrococcus radiodurans and Saccharomyces cerevisiae was investigated. Though these substances are stimulating the development of higher plants, there is no effect on growth and respiration of these microorganisms.
