A new restriction endonuclease from Citrobacter freundii.
CfrI, a new restriction endonuclease of unique substrate specificity, has been isolated from a Citrobacterfreundii strain. The enzyme recognizes a degenerated sequence PyGGCCPu in double-strand DNA and cleaves it between Py and G residues to yield 5' -protruding tetranucleotide ends GGCC.
متن کاملInteraction of cefpirome and a cephalosporinase from Citrobacter freundii GN7391.
The interaction of cefpirome and a cephalosporinase from Citrobacter freundii, including hydrolysis and inhibition, was studied in comparison with those of cefotiam, cefotaxime, and ceftazidime. Cefpirome was hydrolyzed by the enzyme more rapidly at Vmax than were cefotaxime and ceftazidime. However, the low affinity of the enzyme for cefpirome caused a reduction in the hydrolytic rate of cefpi...
متن کاملGenetic Characterization of Atypical Citrobacter freundii
The ability of a bacterial population to survive in different niches, as well as in stressful and rapidly changing environmental conditions, depends greatly on its genetic content. To survive such fluctuating conditions, bacteria have evolved different mechanisms to modulate phenotypic variations and related strategies to produce high levels of genetic diversity. Laboratories working in microbi...
متن کاملComplete Genome of Citrobacter freundii Siphophage Stevie
Citrobacter freundii is an opportunistic pathogen responsible for many urinary tract infections acquired in hospitals and is thus a concern for public health. C. freundii phage Stevie might prove beneficial as a treatment against these infections. The complete genome of Stevie and its key features are described here.
