Abstract

The lytic transglycosylase MltA from Escherichia coli with its membrane anchor and signal sequence deleted has been purified to homogeneity by means of cation-exchange chromatography. The enzyme was crystallized using the hanging-drop vapour-diffusion method. The crystals belong to space group P3(1)21 or P3(2)21, with unit-cell parameters a = b = 103.70, c = 109.84 A and one molecule per asymmetric unit. Crystals diffract to 2.2 A resolution on a synchrotron-radiation source.
