Sv. Pletnev et al., PURIFICATION AND CRYSTALS OF TYROSINE PHENOL-LYASE FROM ERWINIA-HERBICOLA, Biochemistry and molecular biology international, 38(1), 1996, pp. 37-42
New method of purification of tyrosine phenol-lyase from Erwinia herbi
cola has been developed. The enzyme obtained is homogeneous and charac
terised by a specific activity which is three times higher then that d
escribed earlier. Crystals of holoenzyme complexed with monovalent cat
ions have been grown from NaCl, KCl and (NH4)(2)SO4 containing solutio
ns. The crystals belong to P6(2)22 space group. They are stable to the
X-ray radiation and diffract up to 2.6-3.1 A. Asymmetric unit contain
s one subunit of tetrameric molecule.
