Abstract
Disclosed are microbial cells useful for degrading insecticides and chlorinated organics and for the production of a protein which degrades insecticides and chlorinated organics, which microbial cells contain and express a heterologous DNA molecule encoding an insect detoxication protein (e.g., an esterase, a cytochrome p450, a glutathione transferase). Preferably, the host cell is a bacteria which grows in soil (e.g., is from the genera Pseudomonas or Bacillus). Methods of using the cells and proteins and compositions thereof are also disclosed.
Claims8
A cytochrome p450 protein comprising the sequence of SEQ ID NO:4.
Isolated and purified DNA encoding an insecticide resistance associated cytochrome P450, said DNA selected from, the group consisting of:
- (a) DNA encoding Hellothis virescens (F) insecticide resistance associated fat body cytochrome P450, comprising the sequence of SEQ ID NO:3.
- (b) insect DNA encoding a resistance associated cytochrome p450, which complementary strand remains hybridized to DNA of (a) above following a stringent wash of 0.3M NaCl, 0.03M sodium citrate, 0.1% SDS at 60.degree. C.;
- and
- (c) DNA which encodes a resistance-associated cytochrome p450 encoded by (a) or (b) above and which differs from (a) or (b) due to the degeneracy of the genetic code.
Isolated and purified DNA, which encodes Hellothis virescens (F) insecticide resistance associated fat body cytochrome p450 and comprises the sequence of SEQ ID NO:3.
A microbial cell containing and expressing heterologous DNA encoding an insect detoxification protein, said heterologous DNA having the sequence of SEQ ID NO:3.
