RESIDUE NUMBER 102 IS SKIPPED SO THAT THE NUMBERING OF THE
RESIDUES IS CONSISTENT WITH GLUCOAMYLASE FROM ASPERGILLUS
NIGER. RESIDUE NUMBERS 141, 240, 319, 320 AND 445 HAVE THE
AMINO ACID TYPE CORRESPONDING TO THE GLUCOAMYLASE FROM
ASPERGILLUS NIGER, RATHER THAN THAT OF ASPARGILLUS AWAMORI
VAR. KAWACHI. THE RESULTING SEQUENCE DIFFERS FROM THE
ASPERGILLUS NIGER SEQUENCE (PIR REFERENCE ALASG4) AT THE
FOLLOWING POSITION:
