A recombinant expression vector is provided that is capable of expression in a host insect and includes a coding sequence for juvenile hormone esterase that, when expressed, lacks the signal sequence targeting the enzyme to the plasma membrane, and thus the resulting protein is cytoplasmic and non-glycosylated. Recombinant microbe embodiments have improved insecticidal activity because the modified, or truncated, protein builds up in microbe-infected cells within the insect and reduces the time taken for the microbe to kill the host. |
