Three-Dimensional Structure of Phosphoenolpyruvate Carboxylase from Escherichia coli at 2.8Å Resolution
Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) irreversibly catalyzes the carboxylation of phosphoenolpyruvate to form oxaloacetate and inorganic phosphate using Mg2+ as a cofactor.

Spectroscopic and electrochemical properties of two azurins (Az-iso1 and Az-iso2) from the obligate methylotroph Methylomonas sp. strain J and the structure of novel Az-iso2
sp. strain J gives rise to two azurins (Az-iso1 and Az-iso2) with methylamine dehydrogenase (MADH-Mj). The intense blue bands characteristic of Az-iso1 and Az-iso2 are observed at 621 and 616 nm in the visibl...

Flower-predominant expression of a gene encoding a novel class I chitinase in rice (Oryza sativa L.)
A flower-predominant cDNA for a gene, termed OsChia1;175, was isolated from a cDNA library of rice pistils. Northern blot and RT-PCR analyses revealed that the OsChia1;175 gene is highly expressed in floral organ...

Mechanism of metal activation of human hematopoietic prostaglandin D synthase
Here we report the crystal structures of human hematopoietic prostaglandin (PG) D synthase bound to glutathione (GSH) and Ca2+ or Mg2+. Using GSH as a cofactor, prostaglandin D synthase catalyzes the isomerizatio...
