Abstract

L-Arabinose has been described as a gratuitous inducer of the yeast alpha-galactosidase. This has been found to be an artefact resulting from galactose contamination of commercial samples of L-arabinose. The inactivation produced on UDP-glucose 4-epimerase by the pentose does not amplify the inducer activity of contaminating D-galactose.

摘要

L-阿拉伯糖曾被描述为酵母α-半乳糖苷酶的 gratuitous 诱导物。现已发现这是商业L-阿拉伯糖样品中半乳糖污染导致的假象。戊糖对UDP-葡萄糖4-表异构酶产生的失活作用并不会增强污染的D-半乳糖的诱导活性。
