f turgor and for long-term storage (Matile 1978; Marty .. 1980). Analysis of the (electro)chemical potential gradients for solutes across the tonoplast indicate that in many cases (e.g. H., Cl., Na., malate, sucrose) transport into the vacuole is active and therefore dependent on metabolic energy (M作者: DOSE 時間: 2025-3-22 02:25 作者: Innovative 時間: 2025-3-22 08:09
). With the development of the methodology to isolate sealed membrane vesicles from plant cells by Sze (1980), this valuable tool could then be applied to the study of transport across plant membranes. Using this system, a number of laboratories have recently characterized ATP-dependent H+ transport作者: 半圓鑿 時間: 2025-3-22 11:57

The enzyme hydrolyzes ATP, GTP, UTP, and CTP in this order and the Km value for ATP was determined as 0.2 mM. It does not hydrolyze A作者: etidronate 時間: 2025-3-22 13:13 作者: 好開玩笑 時間: 2025-3-22 17:37
