TL;DR: The purification of a specific PSI–IsiA supercomplex is reported, which is abundant under conditions of iron limitation and provides a structural characterization of an additional chlorophyll-containing, membrane-integral antenna in a cyanobacterial photosystem.

TL;DR: In this paper, a novel 14-3-3 binding motif, QQXYpT 948 V, at the C terminus of the H 1 -ATPase was identified and characterized, and the protein kinase activity in the plasma membrane fraction that phosphorylates this threonine residue in the enzyme was identified.

TL;DR: Results suggest that a regulatory loop appears to exist by which sulphate deficiency, through an increase in glucobrassicin turnover and nitrilase 3 accumulation, initiates the production of extra auxin leading to increased root growth and branching, thus allowing the root system to penetrate new areas of soil effectively to gain access to fresh supplies of sulphur.

TL;DR: NIT4 may play a role in cyanide detoxification during ethylene biosynthesis because extracts from senescent leaves of A. thaliana showed higher Ala(CN) hydratase/nitrilase activities than extracts from nonsenescent tissue.

TL;DR: It is suggested that AtST5a is the sulfotransferase responsible for the biosynthesis of tryptophan-derived GSs in vivo.
