Sugar transport: Occurrence of trehalase activity in sugar cane
1David North Plant Research Centre, Indooroopilly, Queensland.
Abstract:
Trehalase activity was detected in extracts of roots, leaves, and stalk tissue from sugar cane. The enzyme was not bound to cell particulates, and had a pH optimum of 6.2 and a Michaelis constant for trehalose of 1×10(-4) M. The level of enzyme detected in mature stalk tissue was too low to account for glucose transport into tissue slices. The enzyme level was high in immature stalk tissue in which the vacuolar sugar pool turns over rapidly. Trehalose synthesis and breakdown may be part of a system for transport of hexose out from the vacuole.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Phloem and Sugar Transport
Secondary Active Transport
Secondary Active Transport
Sugars as Energy Storage Molecules
