Levels of macrophage colony-stimulating factor (nine of nine patients) and gamma interferon (six of nine patients) in serum were elevated above the range of normal in the acute phase of tsutsugamushi...
RecA protein-dependent cleavage of UmuD protein and SOS mutagenesis.
Shinagawa, H, Iwasaki, H, Kato, T, Nakata, A
Induction of the Escherichia coli SOS system increases the ability of the cell to perform DNA repair and mutagenesis. Products of the recA and umuD,C genes are required for mutagenesis induced by...
Escherichia coli RuvC protein is an endonuclease that resolves the Holliday structure.
Iwasaki, H, Takahagi, M, Shiba, T, Nakata, A, Shinagawa, H
Genetic evidence suggests that the Escherichia coli ruvC gene is involved in DNA repair and in the late step of RecE and RecF pathway recombination. To study the biochemical properties of RuvC...
The Escherichia coli polB gene, which encodes DNA polymerase II, is regulated by the SOS system.
Iwasaki, H, Nakata, A, Walker, G C, Shinagawa, H
The dinA (damage inducible) gene was previously identified as one of the SOS genes with no known function; it was mapped near the leuB gene, where the polB gene encoding DNA polymerase II was also...
Fukuoh, A, Iwasaki, H, Ishioka, K, Shinagawa, H
The RecG protein of Escherichia coli is a DNA helicase that promotes branch migration of the Holliday junctions. We found that overproduction of RecG protein drastically decreased copy numbers of...
Physical interactions among circadian clock proteins KaiA, KaiB and KaiC in cyanobacteria.
Iwasaki, H, Taniguchi, Y, Ishiura, M, Kondo, T
The kai gene cluster, which is composed of three genes, kaiA, kaiB and kaiC, is essential for the generation of circadian rhythms in the unicellular cyanobacterium Synechococcus sp. strain PCC 7942....
Ishikawa, M, Mikami, Y, Usukura, J, Iwasaki, H, Shinagawa, H, Morikawa, K
The fatty acid beta-oxidation multienzyme complex from Pseudomonas fragi, HDT, exhibits predominantly the three enzymic activities of 2-enoyl-CoA hydratase (EC 4.2.1.17), 3-hydroxyacyl-CoA...
Tsutsui, Y, Morishita, T, Iwasaki, H, Toh, H, Shinagawa, H
To identify Schizosaccharomyces pombe genes involved in recombination repair, we identified seven mutants that were hypersensitive to both methyl methanesulfonate (MMS) and gamma-rays and that...
Tsutsui, Y, Khasanov, F K, Shinagawa, H, Iwasaki, H, Bashkirov, V I
Schizosaccharomyces pombe Rhp55 and Rhp57 are RecA-like proteins involved in double-strand break (DSB) repair. Here we demonstrate that Rhp55 and Rhp57 proteins strongly interact in vivo, similar to...
Tamatani, T, Tsunoda, H, Iwasaki, H, Kaneko, M, Hashimoto, T, Onozaki, K
We investigated the possible existence of IL-1 in human amniotic fluid (AF). Since AF from most full-term deliveries appeared to contain an inhibitor(s) for thymocyte proliferation, AFs were...
Iwasaki, H., Isayama, T., Johzaki, H., Kikuchi, M.
Using whole cell antigens prepared from the established lines of human malignant fibrous histiocytoma (MFH), the authors have generated two different monoclonal antibodies (FU3 and FU4) by a mouse...
Clinical complications of Mycoplasma pneumoniae disease--other organs.
Suzuyama, Y., Iwasaki, H., Izumikawa, K., Hara, K.
Although self-limited respiratory tract infections caused by Mycoplasma pneumoniae are well recognized in children and young adults, respiratory involvements and hepatic dysfunction may occur. The...
