EFFECT OF DEGLYCOSYLATED EXTENSIN-LIKE PROTEIN ON CELL CULTURE

摘要

Extensin-like proteins(ELP)participate in the construction of plant cell walls,are implicated in interactions between cells connected with molecular recognition,and exhibit protective functions similar to lectins [1,2].Therefore,it seemed interesting to study the role of ELP in cell culture with respect to structure-function relationships.ELP were isolated from 2-day cotton sprouts by extraction with CaCl_2(0.2 M).The resulting proteins were characterized by electrophoresis.The quantitative content of total sugars was determined by spectrophotometry using the anthrone-H_2SO_4 method [3].The carbohydrate content in the isolated samples was 25%.
