structural communications
Crystallization and the structure determination at 1.6 Å resolution of LIPSBS, a thermoalkalophilic lipase from Geobacillus strain SBS-4S, are described. The crystals belonged to orthorhombic space group P212121.
crystallization communications
The enzyme porphobilinogen deaminase (PBGD; hydroxymethylbilane synthase; EC 2.5.1.61) catalyses a key early step in the biosynthesis of tetrapyrroles in which four molecules of the monopyrrole porphobilinogen are condensed to form a linear tetrapyrrole. PBGD from B. megaterium was expressed and the enzyme was crystallized in a form which diffracts synchrotron radiation to high resolution.
