Chemotaxis mutants of Spirochaeta aurantia.
Five Spirochaeta aurantia chemotaxis mutants were isolated. One mutant (the che-101 mutant) never reversed, one (the che-200 mutant) flexed predominantly, two (the che-300 and che-400-1 mutants) exhibited elevated reversal frequencies, and one (the che-400 mutant) exhibited chemotactically unstimulated behavior similar to that of the wild-type strain. The che-101 and che-400 mutants were essent...
متن کاملMotility and chemotaxis of Spirochaeta aurantia: computer-assisted motion analysis.
A computer program has been designed to study behavior in populations of Spirochaeta aurantia cells, and this program has been used to analyze changes in behavior in response to chemoattractants. Three kinds of behavior were distinguished: smooth swimming, flexing, and reversals in direction of swimming after a short pause (120 ms). Cell populations exposed to chemoattractants spent, on average...
متن کاملNucleotide sequence, expression and transcriptional analysis of the Corynebacterium glutamicum gltA gene encoding citrate synthase.
Citrate synthase catalyses the initial reaction of the citric acid cycle and can therefore be considered as the rate-controlling enzyme for the entry of substrates into the cycle. In Corynebacterium glutamicum, the specific activity of citrate synthase was found to be independent of the growth substrate and of the growth phase. The enzyme was not affected by NADH or 2-oxoglutarate and was only ...
متن کاملa contrastive analysis of concord and head parameter in english and azerbaijani
این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
15 صفحه اولUptake of D-xylose and D-glucose by Spirochaeta aurantia.
Uptake of D-[14C]glucose and D-[14C]xylose by Spirochaeta aurantia was demonstrated to be osmotic shock sensitive and to require a high-energy phosphorylated compound rather than a proton motive force. These features are similar to those of binding protein-mediated transport systems in other gram-negative bacteria.
