Find PDB structures and Computed Structure Models (CSM) by combining queries from tools in this suite: Attribute Search, Sequence Similarity, Sequence Motif, 3D Similarity, and 3D Motif with 'AND' logic.
The phasing template was prepared by the CCP4 program chainsaw from the Pyrococcus furiosis Pfu-1397077-001 (PDB entry 1xi9) coordinate file and the Hv (i.e., barley) AlaAT-PfAlaAT sequence alignment.

The protein sample was 12 mg/mL in 20 mM carbonate buffer-pH 10.5, 2.5 mM PLP, 2.5 mM cycloserine, and 2.5 mM DTT. Crystals were obtained using a 0.7 mL well composition of 22(w/v)% polyethylene glycol monomethyl ether (PGME) 5000, 0.1 M MES, 9 (v/v) % tacsimate and a 2 uL sitting drop prepared from equal volumes of protein and well solution., VAPOR DIFFUSION, SITTING DROP, temperature 295K
