Structure and mechanism of the K/H exchanger KefC.

Intracellular potassium (K) homeostasis is fundamental to cell viability. In addition to channels, K levels are maintained by various ion transporters. One major family is the proton-driven K efflux transporters, which in gram-negative bacteria is important for detoxification and in plants is critical for efficient photosynthesis and growth.

Functional characterization of Helicoverpa armigera trehalase and investigation of physiological effects caused due to its inhibition by Validamycin A formulation.

Trehalase catalyzes hydrolysis of trehalose and plays a crucial role in insect metabolism. In the present study, phylogenetic analysis and multiple sequence alignment suggested that H. armigera trehalase-1 (HaTre-1) is closely related to other soluble trehalases with conserved signature features and functional sites.
