TLDR
The structure of HisB in the orthorhombic crystal form was solved by the molecular-replacement method using the crystal structure of its Arabidopsis thaliana counterpart, which shares 47% sequence identity with Rv1601, as the search model.Abstract:
HisB, encoded by open reading frame Rv1601, possesses enzymatic activity as an imidazoleglycerol-phosphate dehydratase in the histidine-biosynthetic pathway of Mycobacterium tuberculosis. A recombinant form of HisB was crystallized in three crystal forms: crystals grown using 20% PEG 1500 as a precipitant belonged to either the cubic space group P432 or the tetragonal space group P4, while an orthorhombic crystal form belonging to space group P21212 was obtained using 15% PEG 5000 and 10 mM MnCl2 as precipitant. The structure of HisB in the orthorhombic crystal form was solved by the molecular-replacement method using the crystal structure of its Arabidopsis thaliana counterpart, which shares 47% sequence identity with Rv1601, as the search model.read more

Solvent content of protein crystals.
TL;DR: An analysis of the solvent content of 116 different crystal forms of globular proteins found that in many cases this range will be sufficiently restrictive to enable the probable number of molecules in the crystallographic asymmetric unit to be determined directly from the molecular weight of the protein and the space group and unit cell dimensions of the crystal.
