30% PEG-monomethyl ether, 200 mM ammomium sulfate, 100 mM MES,10 mM leupeptin, pH 5.6, VAPOR DIFFUSION, SITTING DROP, temperature 291K

Actinomycetes Streptomyces roseus MA 839-A1

THE LEUPEPTIN IS COVALENTLY CONNECTED TO ACTIVE_SITE SER 195 OF THE ENZYME TO FORM A HEMIACETAL.
THERE IS A DISCREPANCY IN THE NORINE AND PDB NUMBERING, AS NORINE COUNTS ACE AND LEU TOGETHER AS ONE RESIDUE. SO THE DBREF WILL REPORT 4 PDB RESIDUES MATCHING NORINE 3 RESIDUE
