oxaloacetate(out) + phosphate(in) + H(+)(in) = oxaloacetate(in) + phosphate(out) + H(+)(out)
oxaloacetate(out) + phosphate(in) + h(+)(in) = oxaloacetate(in) + phosphate(out) + h(+)(out)
oxaloacetate(out) + phosphate(in) + H(+)(in) = oxaloacetate(in) + phosphate(out) + H(+)(out)
oxaloacetate(out) + phosphate(in) + h(+)(in) = oxaloacetate(in) + phosphate(out) + h(+)(out)
