evolution
extended-spectrum beta-lactamases (ESBL)-producing Enterobacteriaceae from spring waters can be a thread to human health. ESBL-producing Enterobacteriaceae were found in four out of 50 sampled spring waters (4/50, 8.0%) and a total of 16 non-duplicate ESBL-producing Enterobacteriaceae are obtained, including 13 Escherichia coli and three Klebsiella pneumoniae strains. All 16 nonduplicate ESBL-producing Enterobacteriaceae isolates harbour genes encoding CTX-M ESBLs, among which six expressed CTX-M-15, five produced CTX-M-14, three produced CTX-M-55 and two expressed CTX-M-27. Four multilocus sequence types (ST) are found and ST131 is the dominant type (8/16, 50.0%). The contamination of ESBL-producing Enterobacteriaceae are present in spring waters of Mountain Tai
malfunction
mutation at the glutamate residues in the omega-loop of SHV-14, i.e. E126, E164, and E167, can considerably modulate the beta-lactam sensitivity and reduce hydrolysis. The mutations in SHV-14 render beta-lactamase inhibitors more efficient. The mutations alter the active site configuration of SHV-14

genotyping and phenotyping of Escherichia coli strains with beta-lactamase activity in faeces from ducks, phylogenetic analysis. In Klebsiella pneumoniae 10, 3, and 4 isolates possess blaTEM, blaSHV, and blaCTX-M genes, respectively. The sequences of selected PCR products are found 98% cognate with blaCTX-M-9, blaSHV-12 and blaTEM-1. 13 Klebsiella pneumoniae isolates (43.33%) are detected as AmpC producers possessing gene blaAmpC. Significantly higher occurrence of beta-lactamase and biofilm producing Enterobacteriaceae isolates is detected in backyard ducks than organized farms
physiological function
New Delhi MBL (NDM)-1 is a clinically significant metallo beta-lactamase
physiological function
84 multidrug-resistant Klebsiella pneumoniae (MDR-KP) clinical isolates studied, 19 isolates exhibit high level resistance to amikacin mediated by the production of the 16S rRNA methylase. CTX-M genes were found in all of the isolates. Among these armA- or rmtB/CTX-M-producing Klebsiella pneumoniae isolates, 31.6% carry the carbapenemase genes (blaKPC-2 [26.3%], blaIMP-4 [10.5%], and blaNDM-1 [5.3%]), which made them resistant to imipenem
physiological function
extensive production of SHV-14 beta-lactamase makes Klebsiella pneumoniae resistant to beta-lactams. The presence of an omega-loop has been reported to influence the beta-lactamase activity, which is also present in SHV-14
additional information
different genotypes of the New Delhi metallo beta-lactamase are identified: the substitutions do not affect the overall folds of the enzyme variants, within limits of detection. Differences in thermal stabilities are observed. kcat/KM values are similar for carbapenem and penicillin substrates for NDM variants, but differences in kinetics are observed for cephalosporin substrates. Apparent substrate inhibition is observed with nitrocefin for variants containing the M154L substitution. In all cases, cefoxitin and ceftazidime are poorly hydrolysed. Clinically observed substitutions can make substantial differences in thermodynamic stability, suggesting that this may be a factor in metallo beta-lactamase evolution. Comparative analysis of the beta-lactam susceptibility of the NDM variants in Escherichia coli, overview

Mox-1 is a unique plasmid-mediated class C beta-lactamase. Structure comparison with other beta-lactamases shows that two region in Mox 1, amino acid residues 214 to 216 positioned in the omega loop and the other in the N-terminus of the B3 beta-strand corresponding to amino acid residues 303 to 306, having significant structural flexibility of these regions, may impact the recognition and binding of substrates in Mox-1 leading to the unique substrate profile of the enzyme, overview.

close to 80% of blaTEM-1 and blaSHV-12 are linked to IS26 while 90% or more of blaCTX-Ms and blaCMYs are linked to ISEcp1. ISAba125 is located upstream of blaNDM-1 and some blaCMY-2 genes. In addition, seven transconjugants are available for further analysis, and armA, qnrS1, acc(6')-Ib-cr, blaCTX-M-15, blaTEM-1, and blaNDM-1 are cotransferred.
