Western blots and TLC scanning results for RhoA63L with radioactive prenyl anchor precursors. Western Blot and corresponding scans from TLC linear analyzer of wildtype GST-RhoA63L-fusion protein translated with [3H]mevalonic acid (lane 1), GST-RhoA63L mutant C190S with [3H]mevalonic acid (lane 2), GST-RhoA63L with [3H]FPP (lane 3) and GST-RhoA63L with [3H]GGPP (lane 4). There is significant incorporation of a product of mevalonic acid (lane 1) as well as of GGPP (lane 4). The signal for FPP attachment is reduced, although more protein is detected (lane 3). This confirms GGPP as preferred substrate.
