Abstract

The putative metal-transporter protein PsaA of Streptococcus pneumoniae is of potential interest both as a vaccine and also as a drug target. The overexpression of the protein in E. coli, and its subsequent purification and crystallization are described. The crystals are rectangular rods and diffract to beyond 2.7 A resolution. The crystal space group is P212121 with unit-cell dimensions a = 59.9, b = 66.5 and c = 69.9 A.
