| therapeutic effect of sf-2103a, a novel carbapenem antibiotic, in combination with cefotaxime, cefoperazone and other cephalosporins. | combinations of sf-2103a with cefotaxime, cefoperazone or cefazolin showed synergistic efficacy at a wide range of combination ratios against experimental infection in mice due to proteus vulgaris gn76/c-1, producing type ic cephalosporinase, escherichia coli no. 29/36 rgn823, producing type iiia (tem-2) penicillinase and e. coli gn206, producing type ib cephalosporinase. these effects by sf-2103a were greater than those seen with sulbactam. the in vitro and in vivo synergistic activities were r ... | 1986 | 3531130 |
| expression and regulation of the penicillin g acylase gene from proteus rettgeri cloned in escherichia coli. | the penicillin g acylase genes from the proteus rettgeri wild type and from a hyperproducing mutant which is resistant to succinate repression were cloned in escherichia coli k-12. expression of both wild-type and mutant p. rettgeri acylase genes in e. coli k-12 was independent of orientation in the cloning vehicle and apparently resulted from recognition in e. coli of the p. rettgeri promoter sequences. the p. rettgeri acylase was secreted into the e. coli periplasmic space and was composed of ... | 1986 | 3531181 |

| aerobic degradation of choline by proteus mirabilis: enzymatic requirements and pathway. | cleavage of choline to trimethylamine and acetaldehyde by extracts of proteus mirabilis requires both particulate and soluble protein fractions, k+, and a bound divalent metal cation. the reaction shows a long lag period, abolished only by preincubation of the particulate fraction in the complete reaction system. the two-carbon fragment produced is acetaldehyde; choline cleavage appears to be tightly coupled to dismutation of the acetaldehyde to ethanol and acetate, as indicated by stimulation b ... | 1986 | 3536045 |
| [interactions of ceftriaxone with beta-lactamases including those which hydrolyze cefotaxime]. | as it occurs with most of 3rd generation cephalosporins, ceftriaxone has few, if any, interactions with penicillinase-type beta-lactamases, such as tem-1, tem-2 or pit-2. these poor interactions are characterized by an extremely low hydrolysis, associated to a poor affinity of these compounds for the penicillinases. conversely, ceftriaxone, as cefotaxime, shows a high affinity for chromosomally-mediated cephalosporinases (indole-positive proteus, enterobacter, pseudomonas...), which is character ... | 1986 | 3537935 |
| properties of an inducible beta-lactamase from proteus vulgaris. | the inducible beta-lactamase of the clinical proteus vulgaris isolate 4917/81 was highly purified by column chromatography and by fplc (cation ion exchange column). molecular weight of the enzyme amounted 33,000 daltons, as revealed by sds-electrophoresis. the enzyme was not inhibited by p-chloromercuribenzoate, but by low concentrations of oxacillin and clavulanic acid. the enzyme inactivated not only penicillin derivatives (including ureidopenicillins), but also first-generation cephalosporins ... | 1986 | 3538717 |
| histochemical and biochemical urease localization in the periplasm and outer membrane of two proteus mirabilis strains. | proteus mirabilis, a gram-negative bacillus, is often implicated in the formation of infectious kidney stones. as ureolytic activity of this organism is thought to play a major role in its pathogenesis, we adapted our recently described urease localization technique to visualize urease activity in vivo. urease activity was ultrastructurally localized in two clinically isolated p. mirabilis strains by precipitating the enzymatic reaction product (ammonia) with sodium tetraphenylboron. subsequent ... | 1986 | 3539291 |
