Separation of the Mg-ATPases from the Ca-Phosphatase Activity of Microsomal Membranes Prepared from Barley Roots.

abstract：:Signals can be perceived and amplified at the cell membrane by receptors coupled to the production of a variety of second messengers, including myoinositol 1,4,5-trisphosphate [Ins(1,4,5)P(3)]. The myoinositol polyphosphate 5-phosphatases (5PTases; EC 3.1.3.56) comprise a large protein family that hydrolyzes 5-phospha...

abstract：:We have proposed that the lateral inequality of auxin associated with the phototropic response is a consequence of a light-induced impairment of basipolar transport of the hormone. If this is so, the dose-response curve for photoinhibition of auxin transport should resemble that for phototropism. Further, the waveleng...
