Purification and some characteristics of enterocin ON‐157, a bacteriocin produced by Enterococcus faecium NIAI 157
Enterocin ON‐157 had a bactericidal mode of action and inhibited the growth of the enterococci, Lactobacillus sake and Listeria monocytogenes and was easily inhibited by treatment with α‐amylase and proteolytic enzymes. Expand
Preliminary X‐ray crystallographic studies of photosynthetic reaction center from a thermophilic sulfur bacterium, Chromatium tepidum
A membrane protein complex, photosynthetic reaction center purified from the thermophilic purple sulfur bacterium, Chromatium tepidum has been crystallized from a phosphate butter containing a detergent and a precipitant, polyethylene glycol 4000, suitable for high‐resolution X‐ray crystallographic studies.

FK 506 assay past and present--characteristics of FK 506 ELISA.
Comparative base specificity, stability, and lectin activity of two lectins from eggs of Rana catesbeiana and R. japonica and liver ribonuclease from R. catesbeiana.
The results indicate that the agglutination sites are not identical with, but are related to, the active sites of the three frog proteins, which are more resistant than RNase A to heat treatment, guanidine-HCl and pH-induced denaturation. Expand
Primary structure of a ribonuclease from bullfrog (Rana catesbeiana) liver.
A pyrimidine base-specific ribonuclease was purified from bullfrog (Rana catesbeiana) liver by means of CM-cellulose column chromatography and affinity chromatography on heparin-Sepharose CL-6B,Expand
Inhibition of DNA methyltransferase by microbial inhibitors and fatty acids.
The results suggest that the length of the carbon chain, the number of double bonds and the presence of a carboxyl group and branched methyl group in the fatty acid molecule may play an important role in the inhibition of DNA methyltransferase. Expand
DMI-2 and DMI-3, DNA methyltransferase inhibitors produced by Streptomyces sp. strain no. 560.
DMI-2 and DMI-3 showed strong inhibition against N6-methyladenine-DNA methyltransferase (M. Eco RI) and Eco RI in a competitive manner with respect to plasmid pUC19 and SAM. Expand
OS1. gastric cancer
It is found that SRPX2 is a novel CSPG that is overexpressed in gastrointestinal cancer cells and is a new member of the cancer-related proteoglycan family. Expand
