The structure of peptidase T, or tripeptidase, was deter-mined by multiple wavelength anomalous dispersion (MAD) methodology and re®ned to 2.4 A Ê resolution. Pep-tidase T comprises two domains; a catalytic domainwith an active site containing two metal ions, and a smaller domain formed through a long insertion into the catalytic domain. The twometal ions, presumablyzinc, are separatedby3.3 AÊ , and are coordinated by ®ve carboxylate and histidine ligands.

Aedes aegyptikynurenine aminotransferase (AeKAT) catalyzes the irrevers-ible transamination of kynurenine to kynurenic acid, the natural antagonist of NMDA and 7-nicotinic acetycholine receptors. Here, we report the crys-tal structure of AeKAT in its PMP and PLP forms at 1.90 and 1.55 A ˚ , respectively. The structure was solved by a combination of single-wave-length anomalous dispersion and molecular replacement approaches.

We solved the crystal structure ofStreptococcus agalactiaeserine⁄threonine phosphatase (SaSTP) using a combination of single-wavelength anomalous dispersion phasing and molecular replacement. The overall structure resem-bles that of previously characterized members of the PPM⁄PP2C STP fam-ily.
