THE AUTHORS STATE THAT THE BIOLOGICAL UNIT IS A INDEFINITELY LONG PAIR OF SHEETS (A PROTOFIBRIL). ONE SHEET FORMED BY CHAINS A AND B AND THEIR CRYSTALLOGRAPHIC TRANSLATIONS ALONG THE "A" CELL DIMENSION (E.G. X,Y,Z AND X+1,Y,Z). THE SECOND SHEET IS CONSTRUCTED FROM -X, Y+1/2,-Z AND THEIR CRYSTALLOGRAPHIC TRANSLATIONS ALONG THE "A" CELL DIMENSION (E.G. -X+1, Y+1/2,-Z).
