Description	The technical formulation of hexachlorocyclohexane (HCH) mainly consists of the insecticidal gamma-isomer and noninsecticidal alpha, beta, and delta-isomers, among which beta-HCH is the most recalcitrant and has caused serious environmental problems. A gamma-HCH-utilizing bacterial strain, Sphingobium sp. MI1205, was isolated from soil which had been contaminated with HCH isomers. This strain degraded beta-HCH more rapidly than the well-characterized gamma-HCH-utilizing strain Sphingobium japonicum UT26. In MI1205, beta-HCH was converted to 2,3,5,6-tetrachlorocyclohexane-1,4-diol (TCDL) via 2,3,4,5,6-pentachlorocyclohexanol (PCHL). A haloalkane dehalogenase LinB (LinB-MI) that is 98 % identical (seven amino-acid differences among 296 amino acids) to LinB from UT26 (LinB-UT) was identified as an enzyme responsible for the two-step conversion of beta-HCH to TCDL. This property of LinB-MI contrasted with that of LinB-UT, which catalyzed only the first step conversion of beta-HCH to PCHL.
