http://purl.uniprot.org/citations/9868772http://www.w3.org/2000/01/rdf-schema#comment"The effect of substitution of asparagine for arginine at position 276 (Ambler's numbering) on the properties of the extended-spectrum beta-lactamase CTX-M-4 was studied. Compared with CTX-M-4, the mutant beta-lactamase CTX-M-4(R276N) conferred lower levels of resistance to cefotaxime, ceftriaxone and aztreonam while the levels of resistance to penicillins and penicillin-inhibitor combinations were similar. Arg-276-->Asn substitution rendered CTX-M-4 slightly less susceptible to inhibition by clavulanate and tazobactam. It also caused a three-fold reduction in the relative rate of hydrolysis of cefotaxime. These results indicate that Arg-276 in CTX-M-type beta-lactamases may be implicated in hydrolysis of oxyimino-beta-lactams; they do not, however, support the hypothesis that Arg-276 is the functional equivalent of Arg-244 found in other class A beta-lactamases."xsd:string
