CRYSTALS OF PEL10ACM WERE GROWN BY VAPOUR-PHASE DIFFUSION USING THE HANGING-DROP METHOD WITH SCREENING AS DESCRIBED BY BRZOZOWSKI & WALTON (2001 [[BRZOZOWSKI, A.M. & WALTON, J. (2001). J. APPL. CRYST. 34, 97-101.]] ). THE PROTEIN CONCENTRATION WAS 30 MG ML-1 IN NA MES BUFFER PH 5.2 CONTAINING KSCN AT A CONCENTRATION OF 200 MM. THE PRECIPITANT WAS 20%(W/V) MONOMETHYL POLYETHYLENEGLYCOL 2000 AND CRYSTALS APPEARED AFTER 2 D AT 291 K
