Phosphorelays
WebAsp phosphorelays have recently received considerable attention because they have been identified as targets for antifungal drugs.13) His-Asp phosphorelays are unique to bacteria, fungi, and higher plants. Recently, we characterized an HK, designated NikA, that is commonly found in many fungi, in association WebJan 17, 2024 · phosphorelay (plural phosphorelays) The multi-stage process, involving the movement of phosphoryl groups by histidine kinases, of bacterial signal transduction; …

WebIn general, TCs are located at strategically important positions for nutrient acquisition and exchange, such as symplasmic/apoplasmic interfaces in vascular tissues and seeds, reproductive and secretory organs and at contact points of plant/symbiotic and plant/parasitic interactions. WebPhosphorelays are signal integration circuits that allow greater levels of control than basic two-component systems by providing more nodes and checkpoints for the input of both positive and negative signals.
WebAug 11, 2010 · Phosphorelays are extended two-component signalling systems found in diverse bacteria, lower eukaryotes and plants. Only few of these systems are characterized, and we still lack a full understanding of their signalling abilities. Here, we aim to achieve a global understanding of phosphorelay signalling and its dynamical properties. WebPhosphorelays. Some histidine kinases are hybrids that contain an internal receiver domain. In these cases, a hybrid HK autophosphorylates and then transfers the …
