THE REMARK MAY ALSO PROVIDE INFORMATION ON REMARK 300 BURIED SURFACE AREA. REMARK 300 REMARK: THE LENTIL LECTIN MOLECULE NORMALLY EXISTS AS A DIMER. THE REMARK 300 TWO MONOMERS IN THIS ENTRY ARE RELATED BY A PSEUDO TWO-FOLD REMARK 300 AXIS. EACH MONOMER CONSISTS OF TWO SEPARATE POLYPEPTIDE REMARK 300 CHAINS, ALPHA AND BETA. THE ALPHA CHAIN CONSISTS OF 181 REMARK 300 RESIDUES AND THE BETA CHAIN CONSISTS OF 52 RESIDUES. THE REMARK 300 ALPHA AND BETA CHAINS OF MONOMER 1 HAVE BEEN ASSIGNED CHAIN REMARK 300 IDENTIFIERS *A* AND *B*, RESPECTIVELY, IN THIS ENTRY. THE REMARK 300 ALPHA AND BETA CHAINS OF MONOMER 2 HAVE BEEN ASSIGNED CHAIN REMARK 300 IDENTIFIERS *C* AND *D*, RESPECTIVELY, IN THIS ENTRY. THIS REMARK 300 NUMBERING SCHEME IS THE SAME AS THAT USED FOR PEA LECTIN REMARK 300 BY EINSPAHR ET AL. (ENTRY 2LTN). THE MONOMERS ARE RELATED REMARK 300 BY A NON-CRYSTALLOGRAPHIC TWO-FOLD AXIS PARALLEL TO THE REMARK 300 CRYSTALLOGRAPHIC B-AXIS. THE TRANSFORMATION PRESENTED ON REMARK 300 *MTRIX* RECORDS BELOW WILL YIELD APPROXIMATE COORDINATES REMARK 300 FOR CHAINS *C* AND *D* WHEN APPLIED TO CHAINS *A* AND *B*, REMARK 300 RESPECTIVELY.
