Thr-154 of the chemoreceptor Tar in Escherichia coli is important for aspartate sensing. Taking advantage of the fact that Tar has no Cys residues, we have further investigated the role of Thr-154 by...
Roles of the Respiratory Na+ Pump in Bioenergetics of Vibrio alginolyticus (1988)
Tokuda, Hajime, Asano, Makoto, Shimamura, Yoshiki, Unemoto, Tsutomu, Sugiyama, Shigeru, Imae, Yasuo
Bioenergetic characteristics of Na+ pump-defective mutants of a marine bacterium Vibrio alginolyticus were compared with those of the wild type and revertant. Generation of membrane potential and...
Purification and Properties of Uridine Diphosphoglucose 4-epimerase from Escherichia coli (1964)
IMAE, YASUO, MORIKAWA, NOBUKO, KURAHASHI, KIYOSHI
A method for purification of UDPglucose 4-epimerase from Escherichia coli was described. An overall purification of 80-fold above the crude extract was achieved. With the use of this partially...
Isolation of Uridine Diphosphogalactose from Escherichia coli Mutant Cells (1964)
MORIKAWA, NOBUKO, IMAE, YASUO, NIKAIDO, HIROSHI
An improved method for the isolation of UDPgalactose from a mutant of Escherichia coli is described. The purity of the preparation is about 95% when it is measured enzymatically and...
Effect of Intracellular pH on Rotational Speed of Bacterial Flagellar Motorsâ€
Minamino, Tohru, Imae, Yasuo, Oosawa, Fumio, Kobayashi, Yuji, Oosawa, Kenji
Weak acids such as acetate and benzoate, which partially collapse the transmembrane proton gradient, not only mediate pH taxis but also impair the motility of Escherichia coli and Salmonella at an...
Sugimoto, Kazunori, Okazaki, Tuneko, Imae, Yasuo, Okazaki, Reiji
Nascent short DNA chains isolated from T4-infected E. coli under a variety of conditions anneal equally to the separated complementary phage DNA strands. The samples examined include: pulse-labeled...
