The aerobic degradation of chloroethene (vinyl chloride) by Mycobacterium aurum strain LI proceeded by initial formation of an epoxide mediated by an alkene monooxygenase (Hartmans and de Bout 1992). This reaction has also been demonstrated to occur with Methylosinus trichosporium, even though subsequent reactions were purely chemical (Castro et al. 1992b). [Pg.365]

In Xanthobacter sp. strain Py2 both the alkene monooxygenase and the epoxidase are induced by C2, C3, and C4 alkenes, and also by chlorinated alkenes including vinyl chloride, cis- and trans-dichlo-roethene and 1,3-dichloropropene (Ensign 1996). [Pg.500]

Indeed, vinyl chloride- and etiiene-grown cells of strain LI have been shown to oxidize propene to 1,2-epoxypropane [30], indicating that alkene monooxygenase was present in cells grown on both the substrates. [Pg.244]

NADH- and os gen-dependent alkene monooxygenase was also detected in dialyzed crude extracts of ethene- and vinyl chloride>grown cells [26]. No monooxygenase activity was detected in cells grown on acetate or succinate. [Pg.245]

The presence of alkene monooxygenase activity in extracts of vinyl chloride-grown M. aurum LI, combined witli the observation that vinyl chloride degradation can be competitively inhibited by the addition of ethene or propene, which are both oxidized to the corresponding epoxides, is strong evidence that the initial step in vinyl chloride metabolism is indeed catalyzed by alkene monooxygenase (Figure 3) [25]. [Pg.245]

In studying the inhibitory effects of the less reactive l,2-epo]ypropane, it was previously demonstrated that the inhibitory effect on the monooiygenases examined was much stronger than on other physiological functions of the cell [31]. Althouf not examined for strain LI, this is probably also the case with alkene monooxygenase inactivation by chlorooxirane. [Pg.245]

Alkene monooxygenase (AMO) from Rhodococcus rhodochrous B-276 (also known as Nocardia corallina) is a multicomponent oxygenase that catalyzes the stereoselective insertion of an oxygen atom from O2 into aliphatic alkenes, yielding the corresponding chiral epoxides (Table 1) [151], This reaction is the first step in the pathway of the alkene metabolism. AMO utilizes substrates ranging from C3-... [Pg.293]
