'''Crystal structure of putative acetolactate synthase- small subunit from Nitrosomonas europaea'''<br />


==Overview==
==Crystal structure of putative acetolactate synthase- small subunit from Nitrosomonas europaea==
Crystal structures of two orthologs of the regulatory subunit of, acetohydroxyacid synthase III (AHAS, EC 2.2.1.6) from Thermotoga maritima, (TM0549) and Nitrosomonas europea (NE1324) were determined by, single-wavelength anomalous diffraction methods with the use of, selenomethionine derivatives at 2.3 A and 2.5 A, respectively. TM0549 and, NE1324 share the same fold, and in both proteins the polypeptide chain, contains two separate domains of a similar size. Each protein contains a, C-terminal domain with ferredoxin-type fold and an N-terminal ACT domain, of which the latter is characteristic for several proteins involved in, amino acid metabolism. The ferredoxin domain is stabilized by a calcium, ion in the crystal structure of NE1324 and by a Mg(H2O)(6)2+ ion in, TM0549. Both TM0549 and NE1324 form dimeric assemblies in the crystal, lattice.

Publication Abstract from PubMed

Crystal structures of two orthologs of the regulatory subunit of acetohydroxyacid synthase III (AHAS, EC 2.2.1.6) from Thermotoga maritima (TM0549) and Nitrosomonas europea (NE1324) were determined by single-wavelength anomalous diffraction methods with the use of selenomethionine derivatives at 2.3 A and 2.5 A, respectively. TM0549 and NE1324 share the same fold, and in both proteins the polypeptide chain contains two separate domains of a similar size. Each protein contains a C-terminal domain with ferredoxin-type fold and an N-terminal ACT domain, of which the latter is characteristic for several proteins involved in amino acid metabolism. The ferredoxin domain is stabilized by a calcium ion in the crystal structure of NE1324 and by a Mg(H2O)(6)2+ ion in TM0549. Both TM0549 and NE1324 form dimeric assemblies in the crystal lattice.
