Protein synthesis during fungal spore germination. IV. Transfer ribonucleic acid from germinated and ungerminated spores.
Transfer ribonucleic acid (tRNA) fractions isolated from germinated and ungerminated spores of Botryodiplodia theobromae and Rhizopus stolonifer had acceptor activity for all 20 amino acids commonly found in protein, when tested with an enzyme fraction from germinated spores. Accordingly, it is unlikely that the absence of tRNA for a particular amino acid limits protein synthesis in fungal spores.
متن کاملProtein synthesis during fungal spore germination. II. Aminoacyl-soluble ribonucleic acid synthetase activities during germination of Botryodiplodia theobromae spores.
The specific activities of 13 aminoacyl-soluble ribonucleic acid (sRNA) synthetases were measured at various time intervals during the germination of Botryodiplodia theobromae conidiospores. The enzyme activities were low or absent in ungerminated spores, and they increased rapidly as germination proceeded. When extracts of the ungerminated spores were prepared with mortar and pestle, very litt...
متن کاملMitochondrial biogenesis during fungal spore germination: effects of the antilipogenic antibiotic cerulenin upon Botryodiplodia spores.
Germination of spores of the fungus Botryodiplodia theobromae was inhibited by the antilipogenic antibiotic cerulenin. The spores remained viable in the presence of the antibiotic, however, and after prolonged incubation they were able to overcome the inhibition. Cerulenin inhibition of germination was reversed by Tween 40 and Tween 60 (derivatives of palmitate and stearate, respectively), but ...
متن کاملBiosynthesis and degradation of storage protein in spores of the fungus Botryodiplodia theobromae.
Muiridin, a spore-specific protein of the fungus Botryodiplodia theobromae, comprises about 25% of the mature pycnidiospore protein. It has an apparent molecular weight of 16,000 to 17,000 and is rich in glutamine, asparagine, and arginine. Muiridin is synthesized in developing spores via a precursor with an apparent molecular weight of 24,000. Two other polypeptides present in young developing...
متن کاملMitochondrial biogenesis during fungal spore germination. Catalytic activity, composition, and subunit biosynthesis of oligomycin-sensitive ATPase in Botryodiplodia.
Mitochondria from dormant spores of the fungus Botryodiplodia theobromae did not contain a functional oligomycinor dicyclohexylcarbodiimide-sensitive adenosine triphosphatase (ATPase); however, this enzyme activity was elaborated rapidly after 120 min of a 240-min germination sequence. The development of oligomycin-sensitive ATPase in germinating spores was abolished by cycloheximide but initia...
