Penaeus vannamei isotrypsins: purification and characterization.
Three isotrypsins from digestive gland of Penaeus vannamei were purified and characterized by molecular, biochemical and kinetic parameters. Purified isotrypsins A, B, and C are glycoproteins with molecular masses between 30.2 and 32.9 kDa, and, therefore similar to other trypsins. The isoelectric points are anionic and different among the three isotrypsins: pH 3.5 for isotrypsin A, pH 3.0 for ...
متن کاملCharacterization of a rediscovered haplosporidian parasite from cultured Penaeus vannamei.
Mortalities of Penaeus vannamei, cultured in ponds in Belize, Central America, began during the last part of the grow-out cycle during the cold weather months from September 2004 through February 2005. Tissue squashes of infected hepatopancreata and histological examination of infected shrimp revealed that the mortalities might have been caused by an endoparasite. To confirm the diagnosis, DNA ...
متن کاملTaura syndrome virus from Penaeus vannamei shrimp cultured in Korea.
Mass mortality occurred among Penaeus vannamei shrimp cultured in Korea in 2004. In an earlier study, we reported white spot syndrome virus (WSSV) as a causative agent of mass mortality of P. monodon shrimp in Korea (Moon et al. 2003; Dis Aquat Org 53:11-13). However, in the present study, we detected Taura syndrome virus (TSV) from the moribund 2004 P. vannamei shrimp by reverse transcription ...
متن کاملEffect of different levels of dietary protein and water salinity on antioxidant enzymes of white leg shrimp (Penaeus vannamei) juveniles
In this study, effect of different levels of dietary protein (25, 35 and 45 per cent) and water salinity (0-3, 12-15 and 32-35 ppt) on antioxidant enzymes of white leg shrimp (Penaeus vannamei) was studied. 324 P.vannamei (with mean weight±SE: 5.55 ± 0.18 gr) were randomly distributed in twenty seven tanks. Experimental shrimps were fed by formulated diets for 56 days and at the end of the expe...
متن کاملcDNA cloning of the lysozyme of the white shrimp Penaeus vannamei.
Lysozyme, an antibacterial protein, has been implicated in innate immunity in invertebrates, but its activity in shrimp remained to be determined. We cloned the white shrimp lysozyme cDNA using a PCR strategy and detected its activity in haemocytes using a lytic-zone assay against Micrococcus luteus. The cloning was based on a reported EST (dbEST BE18831). The deduced amino acid sequence result...
