WebJul 9, 2012 · The putative β-agarase and β-porphyranase genes of Z. galactanivorans were annotated in the Z. galactanivorans genome (sequenced by Genoscope) 7 using the program GenDB . The conserved protein modules were queried against the Pfam database and by BlastP searches against the GenBank TM nr database. WebAnti protonation occurs on the glycosidic oxygen’s antiperiplanar lone pair, thereby removing the stabilizing exo-anomeric effect. This suggests that anti protonation is an enzymic approach for lowering the activation barrier leading to the transition state (Figure 1 centre).
