SEKUEN ASAM AMINO ANTI WHITE SPOT SYNDROME VIRUS (WSSV) PADA UDANG WINDU (PENAEUS MONODON)

Abstrak

This study aimed to determine the amino acid sequence
homology, functional domains, the model prediction
of protein structure and characteristics of genes
encoding anti WSSV in black tiger shrimp (Penaeus
monodon) originated from Indramayu District. The
research method was qualitative descriptive analysis by
comparing the results of PCR isolation of genes encoding
anti WSSV with GenBank sequence data. The results
showed that the sequence gene encoding anti WSSV in
black tiger shrimp DNA originated Indramayu gene
sequences homologous with Penaeus monodon AV gene,
complate cds (no. Accession DQ641258.1) and Penaeus
monodon PMAV (PmAV) mRNA, complete cds (no.
Accession AY3202750.1). C -type lectin is a functional
domain of the amino acid sequences of anti WSSV
in black tiger shrimp. The structure of the protein
encoding anti WSSV (c -type lectin) is characterized by
the presence of a signal peptide, alpha helix clusters, beta
strand and there are in three cells zones. C-type lectin
indicated could help improved the resistance of black
tiger shrimp from Indramayu district against WSSV
and the c -type lectin could be found in various types
of organisms to be developed as an immunostimulatory
substance.
