THE REMARK MAY ALSO PROVIDE INFORMATION ON REMARK 300 BURIED SURFACE AREA. REMARK 300 REMARK: ALPHA-AI IS A DIMERIC MOLECULE (I2) CONSISTING OF TWO REMARK 300 IDENTICAL SUBUNITS. IT BINDS TWO AMYLASE MOLECULES (2E) REMARK 300 TO FORM A DIMERIC COMPLEX E2I2. HOWEVER, THE REMARK 300 CRYSTALLOGRAPHIC ASYMMETRIC UNIT CORRESPONDS TO HALF THE REMARK 300 COMPLEX MOLECULE (EI). IN THIS ENTRY, COORDINATES FOR ALL REMARK 300 ATOMS ARE PROVIDED FOR ONE CHAIN OF AMYLASE AND ONE CHAIN REMARK 300 OF ALPHA-AI.
