TANSLEY REVIEW No 3. THE STRUCTURE AND SYNTHESIS OF PLANT LECTINS.

Lectins are a group of proteins and glycoproteins which possess specific binding sites for particular sugars. They are very abundant in certain plant tissues, for example the seeds of legumes. Although their biological role in plants has not been convincingly explained, details of their structure, synthesis and molecular biology are beginning to emerge. Contents Summary 351 I.
