Enzymatic production of defined chitosan oligomers with a specific pattern of acetylation using a combination of chitin oligosaccharide deacetylases
Planas, Antoni (Planas Sauter); Biarnés Fontal, Xevi; Hamer, Stefanie Nicole; Cord-Landwehr, Stefan; Waegeman, Hendrik; Moerschbacher, Bruno Maria; Kolkenbrock, Stephan (Scientific Reports. Vol.5, 8716 (2015), 2015-03)Chitin and chitosan oligomers have diverse biological activities with potentially valuable applications in fields like medicine, cosmetics, or agriculture. These properties may depend not only on the ... -
Structural-functional analysis reveals a specific domain organization in family GH20 hexosaminidases
Faijes, Magda; Val Cid, Cristina; Biarnés Fontal, Xevi; Planas, Antoni (Planas Sauter) (PLoS ONE. Vol.10, n.5 (2015), e0128075, 2015-05)Hexosaminidases are involved in important biological processes catalyzing the hydrolysis of N-acetyl-hexosaminyl residues in glycosaminoglycans and glycoconjugates. The GH20 enzymes present diverse ... -
Structure-function features of a mycoplasma glycolipid synthase derived from structural data integration, molecular simulations, and mutational analysis
Planas, Antoni (Planas Sauter); Biarnés Fontal, Xevi; Romero, Javier (Romero García); Francisco, Carles (PLoS One. Vol.8, n.12 (2013), e81990, 2013-12)Glycoglycerolipids are structural components of mycoplasma membranes with a fundamental role in membrane properties and stability. Their biosynthesis is mediated by glycosyltransferases (GT) that catalyze ... -
Substrate distortion in the Michaelis complex of Bacillus 1,3–1,4-β-glucanase: insight from first principles molecular dynamics simulations
Planas, Antoni (Planas Sauter); Biarnés Fontal, Xevi; Nieto, Joan; Rovira i Virgili, Carme (Journal of Biological Chemistry. Vol.281, n.3 (2006), p.1432–1441, 2006-01)The structure and dynamics of the enzyme-substrate complex of Bacillus 1,3–1,4-β-glucanase, one of the most active glycoside hydrolases, is investigated by means of Car-Parrinello molecular dynamics ...
