Crystals of UDP-N-acetylglucosamine O-acyltransferase (IpxA) from Esch
erichia coli have been obtained from solutions of sodium/potassium pho
sphate and dimethylsulfoxide. These crystals belong to the cubic space
group P2(1)3 (a = 99.0 Angstrom), diffract X-rays to approximately 2.
5 Angstrom resolution and contain one subunit of the enzyme in the asy
mmetric unit. (C) 1995 Wiley-Liss, Inc.
