The Structure, Function, and Regulation of Starch Synthesis Enzymes SSIII with Emphasis on Maize

Starch biosynthesis is a complex and highly controlled process that requires coordinated activities among multiple enzymes. synthase III (SSIII) the largest protein in starch its function to lengthen long-chain amylopectin synthesis. It potentially affects activity of other key enzymes synthesis through protein–protein interactions; therefore, regulation play predominant role In this review, we summarized main research SSIII including biochemical characteristics, structural features, expression atlas, means. Structural features expressional analysis indicated SSIIIa functional maize endosperm rather than SSIIIb-a SSIIIb-b, even though they are similar tertiary structures. The investigation showed there 13 transcription factors control SSIIIa. Interaction network could be involved with ten conclusion, review considerably extends our understanding provides theoretical basis for improving by maize.
