pubmed-article:15333940 | pubmed:abstractText | DszB is a hydrolase involved in the biodegradation of dibenzothiophene in the soil bacterium Rhodococcus sp. IGTS8. DszB catalyzes the hydrolysis of 2'-hydroxybiphenyl-2-sulfinic acid to sulfite and biphenyl-2-ol. DszB and DszB C27S mutant complexed with biphenyl-2-sulfinic acid were crystallized and preliminary X-ray crystallographic analyses were conducted. The crystals of DszB were found to belong to the orthorhombic P2(1)2(1)2(1) space group, with unit-cell parameters a = 36.7, b = 82.6, c = 139.6 A, and to contain one molecule of DszB in the asymmetric unit. Crystals of DszB C27S complexed with biphenyl-2-sulfinic acid belong to space group C2, with unit-cell parameters a = 153.4, b = 45.9, c = 112.9 A, beta = 115.93 degrees. The calculated Matthews coefficient V(M) for the C2 crystals is approximately 2.3 A(3) Da(-1) if two molecules of DszB are present in the asymmetric unit. | lld:pubmed |
