REMARK 400 PEPTIDE FROM HEN EGG WHITE LYSOZYME (50 - 62) COVALENTLY REMARK 400 ATTACHED TO THE I-AK BETA CHAIN VIA A POLYPEPTIDE LINKER. REMARK 400 THE HETERODIMER WAS EXPRESSED IN CHO CELLS AS A GPI-LINKED REMARK 400 PROTEIN AND ENZYMATICALLY CLEAVED WITH PIPLC. FOR THE I-AK REMARK 400 ALPHA CHAIN, THE FIRST 3 RESIDUES AND LAST 14 RESIDUES REMARK 400 COULD NOT BE TRACED. FOR THE BETA CHAIN, 10 RESIDUES AMINO REMARK 400 TERMINAL TO THE HEL PEPTIDE AND 16 RESIDUES IN THE COVALENT REMARK 400 LINKER WERE DISORDERED, AS WERE 15 RESIDUES AT THE REMARK 400 C-TERMINAL TAIL OF THE BETA CHAIN. THE FIRST TWO RESIDUES REMARK 400 BUILT IN THE BETA CHAIN (GLY B5 AND SER B6) ARE IN FACT REMARK 400 CLONING ARTIFACTS OF THE LINKER CONSTRUCTION, AS THESE REMARK 400 RESIDUES ARE ARG B5 AND HIS B6 IN THE NATURAL I-AK REMARK 400 SEQUENCE.
