Remark 999 | SEQUENCE Leu37, Pro70, Ala72, Ala88, Asn148, Phe151, Lys153, Thr161, Asp165, Thr167, Gly185, ...SEQUENCE Leu37, Pro70, Ala72, Ala88, Asn148, Phe151, Lys153, Thr161, Asp165, Thr167, Gly185, His196, Met202, Gln207, Ser216, Asp225, Asn230, Arg236, Leu238, Leu240, Leu245, Asp249, Met258, Asn297, Asn300, Ile327, Val335, Tyr337, Phe341, Val355, Ile360, Ala362, Thr363, Asn369, His378, Ser386, Asp389, Ala398, Gln415, Arg416 differ from the sequence database. These residues were used on the basis of the electron density map. The difference may be due to the use of different strains of Trichoderma reesei for sequencing and for the X-ray structure. |
