Preliminary X-ray crystallographic analysis of β-­carbonic anhydrase psCA3 from Pseudomonas aeruginosa

Two crystal forms of β-carbonic anhydrase psCA3 from P. aeruginosa were grown. Crystal form A belonged to space group P2₁2₁2₁, with unit-cell parameters a = 81.9, b = 84.9, c = 124.2 Å, and diffracted X-rays to 2.9 Å resolution; crystal form B belonged to space group P2₁2₁2, with unit-cell parameters a = 69.9, b = 77.7, c = 88.5 Å, and diffracted X-rays to 3.0 Å resolution.
