The Serratia marcescens extracellular lipase (LipA) is an enzyme applicable to enantioselective hydrolysis of racemic substrates. The enzyme is secreted through an ATP-binding cassette (ABC) exporter, the Lip system, encoded by the lipBCD genes. The S. marcescens recombinant carrying pLIPE121, which encodes the lipA gene in pUC19, exhibited a higher LipA(More)
The molecular mechanisms of the endogenous circadian clocks that allow most animals to adapt to environmental cycles have recently been uncovered. The draft genome of the ascidian, Ciona intestinalis, a model animal that is close to vertebrates, has been described. However, the C. intestinalis genome lacks the canonical clock genes such as Per, Bmal and(More)
Throughout the history of agriculture, many new crop species (polyploids or artificial hybrids) have been introduced to diversify products or to increase yield. However, little is known about how these new crops influence the evolution of new pathogens and diseases. Triticale is an artificial hybrid of wheat and rye, and it was resistant to the fungal(More)
Influenza is a common infectious disease caused by influenza viruses. Annual epidemics cause severe illnesses, deaths, and economic loss around the world. To better defend against influenza viral infection, it is essential to understand its mechanisms and associated host responses. Many studies have been conducted to elucidate these mechanisms, however, the(More)
We provide a new oligo-microarray for Ciona intestinalis, based on the NimbleGen 12-plex×135k format. The array represents 106,285 probes, which is more than double the probe number of the currently available 44k microarray. These probes cover 99.2% of the transcripts in the KyotoHoya (KH) models, published in 2008, and they contain 81.1% of the entries in(More)

For undergraduate .He supervises 31 students of PhD course and 2 students in Master course in Graduate School of Medical and Dental Sciences and 6 students of PhD course and 12 students in Master course in Biomedical Science PhD Program. He is a principle(More)
A circadian rhythm is a roughly 24-h cycle in biological processes and physiological phenomena such as sleep, feeding, and photosynthesis for many organisms on Earth. The circadian patterns are coordinated by rhythmical gene expression of clock genes. Time-course transcriptomic analyses involving statistical methods have shown coordination of periodic gene(More)
We have isolated a lipase-overproducing mutant, GE14, from Serratia marcescens 8000 after three rounds of N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis. The mutant GE14 produced 95 kU/ml of extracellular lipase in the lipase medium, which was about threefold higher than that of produced by the original strain 8000. Enzymatic characteristics including(More)
