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.
