Crystal structure of Acetamidase, putative (tm0119) from THERMOTOGA MARITIMA at 2.50 A resolution

10.0% Glycerol, 5.0% PEG-3000, 30.0% PEG-400, 0.1M Citrate, pH 7.5, VAPOR DIFFUSION,SITTING DROP,NANODROP, temperature 277K

1. HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS
2. A MET-INHIBITION PROTOCOL WAS USED FOR SELENOMETHIONINE
INCORPORATION DURING PROTEIN EXPRESSION. THE OCCUPANCY OF THE
SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.75 TO ACCOUNT FOR
THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION.
3. CL MODELED BASED ON ELECTRON DENSITY.
4. ZINC ATOMS MODELED BASED ON ANOMALOUS PEAKS. COULD ALSO BE
NICKEL OR COPPER.
5. RESIDUE VAL 185 IS A RAMACHANDRAN OUTLIER IN ALL FOUR CHAINS,
AND IS SUPPORTED BY THE DENSITY.
6. RAMACHANDRAN OUTLIERS B93, B94, AND C39 ARE LOCATED IN
WEAK DENSITY.
