REMARK 400 REMARK 400 COMPOUND REMARK 400 GLUCOAMYLASE-471 IS A NATURAL PROTEOLYTIC FRAGMENT OF REMARK 400 PARENT GLUCOAMYLASE, WHICH IS INITIALLY SECRETED BY FUNGI. REMARK 400 GLUCOAMYLASE-471 LACKS THE STARCH-BINDING DOMAIN AND A PART REMARK 400 OF THE O-GLYCOSYLATED LINKER DOMAIN. THE ACTUAL LENGTH OF REMARK 400 GLUCOAMYLASE-471 FROM ASPERGILLUS AWAMORI VAR. X100 IS REMARK 400 NOT DETERMINED EXACTLY. THE CRYSTALLOGRAPHICALLY OBSERVED REMARK 400 LENGTH VARIES BETWEEN 471 AND 473 RESIDUES. REMARK 400 REMARK 400 THE SEQUENCE USED IS THAT OF GLUCOAMYLASE FROM ASPERGILLUS REMARK 400 AWAMORI VAR. KAWACHI (SEE JRNL AND REFERENCE 4). RESIDUE REMARK 400 NUMBERS ARE DISCONTINUOUS. RESIDUE NUMBER 102 IS SKIPPED REMARK 400 SO THAT THE NUMBERING OF THE RESIDUES IS CONSISTENT WITH REMARK 400 GLUCOAMYLASE FROM ASPERGILLUS NIGER. RESIDUE NUMBERS 141, REMARK 400 240, 319, 320, AND 445 HAVE THE AMINO ACID TYPE REMARK 400 CORRESPONDING TO THE GLUCOAMYLASE FROM ASPERGILLUS NIGER, REMARK 400 RATHER THAN THAT OF ASPERGILLUS AWAMORI VAR. KAWACHI. REMARK 400 REMARK 400 THE POLYPEPTIDE CHAIN FOLDS INTO AN ALPHA/ALPHA-BARREL, REMARK 400 COMPRISING 12 HELICES.

THE LAST TWO RESIDUES REMARK 600 OF THE REDUCING END PRESENT IN TWO ALTERNATE CONFORMATIONS, REMARK 600 ONE OF WHICH (OCCUPANCY 0.47) CORRESPONDS TO THE REMARK 600 CONFORMATION OF THE INHIBITOR OBSERVED AT PH 6.0.

REMARK 700 REMARK 700 SHEET REMARK 700 MOST OF THE SHEETS FOR GLUCOAMYLASE-471 ARE HAIRPIN LOOPS REMARK 700 THAT CONNECT HELICES. THESE LOOPS HAVE TWO OR MORE H-BONDS REMARK 700 BETWEEN THE ANTIPARALLEL STRANDS THAT COMPRISE THEM. IN REMARK 700 ADDITION INDIVIDUAL LOOPS PACK TOGETHER, BUT THERE EXISTS REMARK 700 GENERALLY ONLY ONE H-BOND BETWEEN A LOOP AND ITS NEIGHBOR.
