Metallocarboxypeptidase is a crucial enzyme in the digestive tract of insect,and maybe contributes to the processes of insect metamorphosis,development,and resistance. Based on the whole genome database of silkworm( Bombyx mori),metallocarboxypeptidase genes in silkworm were identified by the methods of homology search and hidden Markov model. The predicted results showed that there are 22 metallocarboxypeptidase genes in silkworm and the deduced amino acid sequences all had a zinc ion binding site and cons...
