d-Amino acid dehydrogenase from Helicobacter pylori NCTC 11637
Helicobacter pylori is a microaerophilic bacterium, associated with gastric inflammation and peptic ulcers. d-Amino acid dehydrogenase is a flavoenzyme that digests free neutral d-amino acids…
Alanine racemase from Helicobacter pylori NCTC 11637: purification, characterization and gene cloning.
Isolation and geosmin production of bacteria-free Anabaena macrospora.
Isolation of the bacteria-free clone of Anabaena macrospora from unialgal culture was attemped by using such four methods as UV irradiation, capillary-pipette washing, akinete dilution and akinete…
Cytotoxic effects of scirpene compounds, fusarenon-X produced by Fusarium nivale, dihydronivalenol and dihydrofusarenon-X, on HeLa cells.
Fusarenon-X, isolated from culture filtrate of Fusarium nivale, showed a complete inhibition of growth of HeLa S3 cells at a concentration of 0 .5 ƒÊg/ml.

This work shows that nitrogen fixation can also be achieved by using a non-metallic buckminsterfullerene (C60) molecule, in the form of a water-soluble C60:γ-cyclodextrin (1:2) complex, and light under nitrogen at atmospheric pressure.
Synthesis of dinuclear complexes bearing metalloporphyrin-phosphine hybrid ligands and their catalytic activity toward hydrosilylation of ketones
A new type of metalloporphyrin−phosphine hybrid ligand (1) has been designed and synthesized. Reactions of some transition metal complexes such as PdCl2, PtCl2, and [RhCl(CO)2]2 with a zinc…
Purification and Characterization of Serine Racemase from a Hyperthermophilic Archaeon, Pyrobaculum islandicum
Srr is a homotrimer of a 44,000-molecular-weight subunit, similar to Pyrobaculum aerophilum IlvA, but less than 32% similar to any other serine racemases and threonine dehydratases.
