Iron stress repressed RNA reduces the expression of the protein IsiA, which is also known as CP43, in this structure.
Stress-related inhibition of repairs to this structure is reduced by glycinebetaine, and the serine proteases Deg1 and FTsH are integral to repairing degradation of it. Iron stress repressed RNA reduces the expression of the protein IsiA, which is also known as CP43, in this structure. Nitrogen-fixing cyanobacteria completely lack this complex, whose D1 subunit contains coenzymes like pheophytin. Four manganese ions and a divalent calcium ion form its oxygen evolving complex, where water splitting occurs. Electrons are shuttled to cytochrome b6f by plastoquinol before reaching plastocyanin after passing through this complex, where they are removed from P680 upon antenna pigments' absorption of light in this complex. For 10 points, name this chlorophyll-containing protein complex that is the location of the first step of the light-dependent reactions.
