name: glycogen phosphorylase, muscle form, initiator methionine removed phosphorylated and pyridoxal phosphate lysine 1 (human)
def: "A glycogen phosphorylase, muscle form (human) that has had the initiator methionine removed and that has been phosphorylated on the residue at the position equivalent to Ser-15 and pyridoxal phosphate lysine on the residue at the position equivalent to Lys-681 of the amino acid sequence represented by UniProtKB:P11217-1. Example: UniProtKB:P11217-1, 2-842, Ser-15, MOD:00046|Lys-681, MOD:00128." [PRO:DNx, Reactome:R-HSA-71512]
