The polypeptide chain fold in tyrosine phenol-lyase, a pyridoxal-5'-phosphate-dependent enzyme.


The tyrosine phenol lyase (EC from Citrobacter intermedius has been crystallised in the apo form by vapour diffusion. The space group is P2(1)2(1)2. The unit cell has dimensions a = 76.0 A, b = 138.3 A, c = 93.5 A and it contains two subunits of the tetrameric molecule in the asymmetric unit. Diffraction data for the native enzyme and two heavy… (More)
