Table 1. GAP activity is required for full EAT-17 function.

	No. rescued	Total no. examined	% rescue
Wild-type eat-17 construct	16	76	21
R116K	2	49	4.1
R116A	1	64	1.6

eat-17 mutants were injected with DNA constructs encoding either wild-type or one of two mutant versions (R116K or R116A) of the EAT-17 protein (see Materials and Methods). F₁ transgenic progeny were blindly assayed for rescue of grinder defects. GFP was used to identify transgenic progeny afterward.
