All values are means ±SD. ^a is significantly different from the wild type (bold), ^b is significantly different from fkd1 (mutant combinations with fkd1 that are statistically different from fkd1 are underlined), ^c is significantly different from single mutants, ^d is different from double mutants, and ^e is different from the triple mutant. * represents a significant difference from one of the tested double mutants, but not all.
