Figure 1
The TIM barrel of triosephosphate isomerase. The side chains Lys13 (loop-1), His95 (loop-4) and Glu167 (loop-6) identify the catalytic site. The loops at the catalytic end are coloured green; the loops at the stability end are coloured grey. In A-TIM loop-1, loop-3 and loop-8 have been shortened. The extended new binding pocket of A-TIM between loop-7 and loop-8, which has been generated because of the loop-8 shortening, is marked with an asterisk. The N-terminus and C-terminus are labelled N and C, respectively. |
