Studies on carbohydrate-metabolising enzymes. Part XXI. The α-glucosidase and d-enyme activity of extracts of carrots and tomatoes

Research output: Contribution to journalArticle

Abstract

Extracts of carrot roots and tomato fruits show a range of carbohydrase activities, including substantial maltase, nigerase, and isomaltase activity. In addition, the extracts unexpectedly showed disporportionation activity ith maltotriose and higher maltosaccharides. This latter activity (D-enzyme) can be separated from the a-glucosidases by continuous electrophoresis. The purified D-enzymes show a similar catalytic activity to the corresponding potato enzyme, but differ in optimum pH and other properties. © 1969.
