VC11: an actinophage virulent to Streptomyces cattleya and Streptomyces olivaceus. 1986

V E Coyne, and R Kirby

Five soil samples were screened for the presence of a virulent actinophage. Phage VC11 was found to be virulent on Streptomyces olivaceus, S. cattleya, S. chartreusis, S. griseus (all important beta-lactam antibiotic producers), S. ambofaciens, S. parvulus, S. alboflavus, S. aureofaciens, and S. lividans TC10. Although restriction-modification systems have been observed in S. olivaceus and S. cattleya, the phage EOP on these hosts remained relatively constant, indicating that these systems do not affect VC11.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D004262	DNA Restriction Enzymes	Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.
