STP — Solanum tuberosum
Summary
PGSC0003DMG400028382, designated STP (synonyms StSTP-1, PHS1, PHSL1, STP-1, StPHS1, StPHSL1) on potato chromosome 5, encodes a protein with glycogen phosphorylase activity, 1,4-alpha-oligoglucan phosphorylase activity, pyridoxal phosphate binding, and transglycosidase activity (EC 2.4.1.1). The protein localises to amyloplasts, chloroplast stroma, plastids, and cytosol. STP is associated with starch breakdown and anabolism, glycogenolysis, sucrose and L-arabinose breakdown, carbon catabolite repression, cellular respiration, fermentation, lipogenesis, protein processing and secretion, ribosome biogenesis, appressorium formation, sporulation, and mating. It is linked to starch content and, through related genes in other species, the family has been connected to starch degradation and leaf lesions with cell-specific starch accumulation.
