Auxiliary proteins of photosystem II: tuning the enzyme for optimal
... The core of Photosystem II (PS II) is made up of two reaction center proteins, D1 (PsbA) and D2 (PsbD) and two chlorophyll a-binding antenna proteins, CP47 (PsbB) and CP43 (PsbC). These proteins have homologues in anoxygenic photosynthetic bacterial reaction centers; however, PS II has an increased ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
