Abstract Background A number of membrane-spanning proteins possess enzymatic activity and catalyze important reactions involving proteins, lipids or other substrates located within or near lipid bilayers.Alkaline ceramidases are seven-transmembrane proteins that hydrolyze the amide bond in ceramide to form sphingosine.Recently, a group of putative
The production of carbon-neutral fuels through clean energy has been defined as a target by the European Union and by several international institutions.If the concepts are available, hydrogen, in particular, is considered to be one of the most target-oriented, ecologically and economically Horse Boots realizable approaches.In terms of safety, long
