HEADER HYDROLASE 31-DEC-69 7AJI TITLE bovine ATP synthase dimer state3:state2 COMPND MOL_ID: 2; COMPND 2 MOLECULE: ATP synthase subunit alpha, mitochondrial; COMPND 3 CHAIN: A, B, C, AA, AB, AC; COMPND 4 Residue 1 of chains A, B, C. The uniprot database is misleading COMPND 5 OTHER_DETAILS: stating that GLN is the first residue. The DNA sequence for this COMPND 6 protein encodes GLU. The actual residue is pyroGLU. However pyroGLU COMPND 7 and pyroGLN are the same. Residue 481 in chains A, B, and C can be COMPND 8 Gly or SER. e.g. in this structure should be GLY. We have seen SER in COMPND 9 some of our previous structures of bovine F1-ATPase. We have used the COMPND 10 following REMARK in other PDB files: Microhetrogeneity REMARK 999 SER COMPND 11 481 GLY IN CHAINS A, B AND C REMARK 999 WAS IDENTIFIED AS A GLY FROM COMPND 12 THE PROTEIN REMARK 999 SEQUENCE. IN THE CDNA SEQUENCE, THE CODON FOR COMPND 13 THIS REMARK 999 RESIDUE WAS AGC SER IN THREE CLONES WHILE IN TWO COMPND 14 REMARK 999 OTHERS IT WAS GGC GLY. THE DIFFERENCE WAS THOUGHT TO COMPND 15 REMARK 999 BE DUE TO A MUTATION OCCURRING DURING EITHER PROPAGATION COMPND 16 REMARK 999 OF THE CLONES IN THE LIBRARY OR SUBCLONING INTO M13 REMARK COMPND 17 999 VECTORS. THE ELECTRON DENSITY SUGGESTS A GLY IN REMARK 999 THIS EXPDTA ELECTRON MICROSCOPY DBREF 7AJI A 1 510 UNP P19483 ATPA_BOVIN 44 553
