Studies on carbohydrate-metabolizing enzymes. Trans-β-glucosylation by barley enzymes

Abstract
Extracts of ungerminated barley catalyse the synthesis of oligosaccharides from cellobiose. The oligosaccharides have been isolated and characterized. They include gentiobiose, laminaribiose, gentiobiose, cellotriose and 62-0-glucosylcellobiose. The acceptor specificity of the barley enzymes and similar enzymes from other biological sources is discussed.
