چکیده
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.

Detection of the Klebsiella pneumoniae carbapenemase type 2 Carbapenem-hydrolyzing enzyme in clinical isolates of Citrobacter freundii and K. oxytoca carrying a common plasmid.
The Klebsiella pneumoniae carbapenemase (KPC) was detected in carbapenem-resistant isolates of Citrobacter freundii and Klebsiella oxytoca recovered from different patients in a Michigan hospital. Restriction analysis and hybridization with a KPC-specific probe showed the bla(KPC-2) genes of these two genera of the family Enterobacteriaceae are carried on a common plasmid.
متن کاملPrediction of two- and three-amino-acid sequences of Citrobacter Freundii beta-lactamase from its amino acid composition.
The repeated amino-acid sequences in Citrobacter Freundii beta-lactamase may be indispensable for its function, because such repetitions cannot be simply attributed to a chance. In order to fully explore the functional units in Citrobacter Freundii beta-lactamase, it may need to analyse all the amino acid pairs, triplets, etc. along Citrobacter Freundii beta-lactamase from one terminal to the o...

متن کاملComplete Genome Sequence of Citrobacter freundii Myophage Mordin
Citrobacter freundii and other Gram-negative opportunistic pathogens necessitate concern from the public health sector. Bacteriophages that kill such pathogens may be useful in the control and containment of these infections. Here, we describe the genome of a newly isolated T4-like myophage of C. freundii, Moon, and present its features.
متن کاملComplete Genome Sequence of Citrobacter freundii Myophage Michonne
Citrobacter freundii is a Gram-negative opportunistic pathogen that causes dangerous infections such as neonatal meningitis. C. freundii also harbors antibiotic resistance, making phages infecting this host valuable tools. Here, we announce the complete genome of the C. freundii FelixO1-like myophage Michonne and describe its notable features.
