Dihydrodipicolinate synthase from the plant pathogen A. tumefaciens has been cloned, expressed, purified and crystallized in its unliganded form, in the presence of its substrate pyruvate and in the presence of pyruvate and the allosteric inhibitor lysine. Diffraction data for the crystals were collected to a maximum resolution of 1.40 Å.

Dihydrodipicolinate synthase (DHDPS) catalyzes an important step in lysine biosynthesis. Here, the crystallization and preliminary diffraction analysis to 1.2 Å resolution of DHDPS from C. botulinum in the presence of its substrate pyruvate is reported.

Dihydrodipicolinate synthase from the common grapevine V. vinifera has been cloned, expressed, purified and crystallized in the presence of the substrate pyruvate by in-drop hexahistidine-tag cleavage. A diffraction data set has been collected to a resolution of 2.2 Å.

A clear narrative of complex structure determination, including crystallographic problems of pseudo-merohedral twinning, pseudo-translational symmetry and data anisotropy, is provided. This manuscript provides a description of how these issues encountered during the structural determination of E. coli type I pyruvate kinase to 2.28 Å resolution were overcome.

N-Acetylneuraminate lyase, an enzyme involved in the bacterial uptake and metabolism of sialic acid, is a promising target for antibiotic development against pathogenic bacteria. Here, the cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of N-acetylneuraminate lyase from methicillin-resistant S. aureus to 1.70 Å resolution are reported.
