Because there are tens of parameters that can be varied in the program there is no such a thing as the<br />

DOCK run for a given protein target. We chose to perform two parallel runs that differ in receptor<br />

description. In run 1 the DOCK sphere center description was used while in run 2 the atomic coordinates<br />

of 2'- deoxy-2'-(3-methoxybenzamido)adenosine, a designed selective inhibitor of T. brucei GAPDH<br />

(see Section IV), were picked to describe the receptor site. For each run the same program parameters<br />

were chosen (Table 6) and the ACD database was split up in batches of 10,000 molecules. The<br />

computation was done on an Indigo2 workstation with an R4400 processor operating at 175 MHz. It<br />

took 3 h 19 min of CPU time for run 1 and 34 h 48 min for run 2. The ten-fold time difference between<br />

the two runs originates from the different number of<br />
