| 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 |

| initiation of deoxyribonucleic acid replication in a temperature-sensitive mutant of b. subtilis: evidence for a transcriptional step. | a mutant of bacillus subtilis unable to initiate a new round of replication at 45 c has been described. here we show that inhibition of dna synthesis in this mutant is reversible and that dna synthesis is resumed at low temperature, even in the presence of chloramphenicol. initiation of a new replication cycle thus can occur in the absence of protein synthesis. a thermolabile component required for initiation therefore appears to be synthesized at 45 c in an inactive form and can be activated at ... | 1973 | 4200838 |

| coupling of glycosaminoglycans to agarose beads (sepharose 4b). | 1. heparin, heparan sulphate, chondroitin sulphate and dermatan sulphate were covalently attached to beads of agarose activated by cyanogen bromide. the bond is probably mediated by the amino group of a serine or peptide residue at the reducing end of the polysaccharide chain. 2. the uptake of glycosaminoglycan during the coupling procedure is about 0.9mg/ml of wet gel. however, direct analysis of washed and freeze-dried gels reveals that only about one-third of this amount is firmly attached to ... | 1971 | 4257093 |
