[Identification of two plasmids isolated from a bacteriocinogenic strain of Clostridium perfringens]. 1976

H Ionesco, and G Bieth, and C Dauguet, and D Bouanchaud

Two plasmids were found and studied in the bacteriocinogenic strain N5 of Clostridium perfringens: one is a bacteriocinogenic factor (MW=5.7 X 10(6)) and the other a cryptic plasmid (MW 32.4 X 10(6)). Simultaneous loss of the ability to produce bacteriocin and of the bacteriocin resistance in a "cured" variant corresponds to the loss of the bacteriocinogenic plasmid DNA. The syntheses of haemolysin 0 and phospholipase C do not seem to be coded for by the cryptic plasmid.

UI	MeSH Term	Description	Entries
D010740	Phospholipases	A class of enzymes that catalyze the hydrolysis of phosphoglycerides or glycerophosphatidates. EC 3.1.-.	Lecithinases,Lecithinase,Phospholipase
D010957	Plasmids	Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS.	Episomes,Episome,Plasmid
D003016	Clostridium perfringens	The most common etiologic agent of GAS GANGRENE. It is differentiable into several distinct types based on the distribution of twelve different toxins.	Clostridium welchii
