REMARK 400 REMARK 400 COMPOUND REMARK 400 TYROSTATIN IS A NATURAL INHIBITOR, COMPOSED OF REMARK 400 ISOVALERYL-TYROSYL-LEUSYL-TYROSINAL. REMARK 400 REMARK 400 IN 1GA1 AND 1GA4, THE PROTEIN WAS CRYSTALLIZED WITH THE REMARK 400 VARIANT OF THIS INHIBITOR, WHERE THE SECOND TYR HAD IODINE REMARK 400 INSTEAD OF HYDROXYL, SO IN FACT IT IS P-IODOPHENYLALANINE. REMARK 400 IN 1GA6, TYR WAS USED. WHAT THE AUTHORS OBSERVED IN 1GA4, REMARK 400 WAS THE TRIPEPTIDE NOT TETRAPEPTIDE, LACKING THE LEU RESIDUE REMARK 400 BETWEEN TWO AROMATIC RESIDUES. THIS IS CERTAIN, BUT IT IS REMARK 400 NOT CLEAR HOW SUCH A MODIFIED ENTITY ENDED UP IN THE REMARK 400 STRUCTURE, AS DISCUSSED IN THE PRIMARY REFERENCE. IN 1GA1 REMARK 400 AND 1GA6 ONLY PARTS OF THE INHIBITOR (PARTIALLY OCCUPIED AS REMARK 400 WELL) ARE VISIBLE IN THE ELECTRON DENSITY AND ARE MODELED REMARK 400 AS A TYROSINE IN 1GA6 AND IODOPHENYLALANINE IN 1GA1 REMARK 400 ACCOMPANIED BY JUST MAIN CHAIN PARTS OF ADJOINING RESIDUES, REMARK 400 THEREFORE REPRESENTED AS UNK, UNKNOWNS. IN 1GA6 THERE REMARK 400 WAS NO DENSITY FOR THE RESIDUE EXPECTED TO BIND TO THE REMARK 400 N-TERMINUS OF THE AROMATIC. THE IDENTIFICATION OF IODINE REMARK 400 IN 1GA1 WAS CONFIRMED UNEQUIVOCALLY BY ITS ANOMALOUS REMARK 400 SCATTERING SIGNAL IN THE ANOMALOUS FOURIER MAP. REMARK 400 REMARK 400 THEREFORE IN 1GA4 THE AUTHORS CALLED THE MODIFIED INHIBITOR, REMARK 400 LACKING LEU IN THE MIDDLE, AS "PSEUDOIODOTYROSTATIN". IN TWO REMARK 400 OTHER STRUCTURES THE AUTHORS ARE NOT SURE WHAT IS REALLY REMARK 400 THERE, SO THE INHIBITOR IS DESCRIBED AS "FRAGMENTS OF REMARK 400 IODOTYROSTATIN" IN 1GA1 AND "FRAGMENTS OF TYROSTATIN" REMARK 400 IN 1GA6.
