Unique gangliosides synthesized in vitro by sialyltransferases from marine bacteria and their characterization: ganglioside synthesis by bacterial sialyltransferases
On the basis of the results outlined in our previous report, bacterial sialyltransferases (ST) from marine sources were further characterized using glycosphingolipids (GSL), especially ganglio-series GSLs, based on the enzymatic characteristics and kinetic parameters obtained by Line weaver-Burk plots. Among them, GA1 and GA2 were found to be good substrates for these unique STs. Thus, new gang...
متن کاملMarine Bacterial Sialyltransferases
Sialyltransferases transfer N-acetylneuraminic acid (Neu5Ac) from the common donor substrate of these enzymes, cytidine 5'-monophospho-N-acetylneuraminic acid (CMP-Neu5Ac), to acceptor substrates. The enzymatic reaction products including sialyl-glycoproteins, sialyl-glycolipids and sialyl-oligosaccharides are important molecules in various biological and physiological processes, such as cell-c...
متن کاملPurification of Marine Bacterial Sialyltransferases and Sialyloligosaccharides
Sialic acids are important components of carbohydrate chains and are usually found at the terminal position of the carbohydrate moiety of glycoconjugates (Angata & Varki, 2002; Schauer, 2004). Sialyloligosaccharides of glycoconjugates play important roles in many biological processes (Gagneux & Varki, 1999; Varki, 1993). The transfer of sialic acids to carbohydrate chains is performed by specif...
متن کاملAntibacterial Activity of Tunichrome Released from phallusia nigra Marine Tunicate Obtained from Bushehr Coast
Background: Marine life has long been used for their bioactive compounds. Several amazing compounds with different biological activities have so far been identified in tunicates. The aim of the current study was to evaluate the antimicrobial activity of tunichrome released from phallusia nigra marine tunicates collected from Bushehr province coasts, against four strains of Staphylococcus aure...
متن کاملBioactive Compounds from Marine Bacteria and Fungi
Marine bacteria and fungi are of considerable importance as new promising sources of a huge number of biologically active products. Some of these marine species live in a stressful habitat, under cold, lightless and high pressure conditions. Surprisingly, a large number of species with high diversity survive under such conditions and produce fascinating and structurally complex natural products...
