TITLE 1.27 A CRYSTAL STRUCTURE OF NITROPHORIN 4 FROM RHODNIUS TITLE 2 PROLIXUS COMPLEXED WITH IMIDAZOLE
COMPND MOL_ID: 1; COMPND 2 MOLECULE: NITROPHORIN 4; COMPND 3 CHAIN: A; COMPND 4 ENGINEERED: YES; COMPND 5 OTHER_DETAILS: IMIDAZOLE OCCUPIES THE FE SIXTH COMPND 6 COORDINATION POSITION THE HEME IS DISORDERED BY A ROTATION COMPND 7 OF 180 DEGREES AROUND THE CHA-FE-CHC AXIS. THE ONLY COMPND 8 EVIDENCE OF THIS DISORDER IS THE APPEARANCE OF METHYL COMPND 9 GROUPS CMB AND CMC AS VINYLS. THESE EXTRA ATOMS ARE CALLED COMPND 10 CBBB AND CBCB. THE LOOP CONTAINING RESIDUES 125-130 IS COMPND 11 DISORDERED. IT HAS BEEN BUILT IN TWO POSITIONS, BUT THIS COMPND 12 MODEL DOES NOT COMPLETELY EXPLAIN THE ELECTRON DENSITY.
