Figure 2
(a) A ribbon diagram of the TIM-barrel fold of the ALAD monomer with its pronounced N-terminal arm and two active-site lysines shown in ball-and-stick representation. (b) The assembly of ALAD monomers (coloured differently) to form dimers and (c) the organization of the functional ALAD octamer. This figure and others similar were prepared using the programs MOLSCRIPT (Kraulis, 1991) and BOBSCRIPT (Esnouf, 1997). |
