The electron donor side of photosystem II: the oxygen evolving complex.
The 02-evolving complex (OEC) of photosynthesis resides near the inner side of the thylakoid membrane. Currently, it is believed to be composed of at least four polypeptides: (1) an intrinsic 27-34 kilodalton (kD) polypeptide that may be associated with manganese (Mn) ; (2) a peripheral 33 k D polypeptide, perhaps also associated with Mn; (3) a peripheral 24 kD polypeptide; and (4) a peripheral...
متن کاملar X iv : h ep - p h / 97 02 44 2 v 1 2 7 Fe b 19 97 R b in Supergravity Grand Unification with Non - universal Soft SUSY Breaking
An analysis of supersymmetric contributions to Rb in supergravity grand unification with non-universal boundary conditions on soft SUSY breaking in the scalar sector is given. Effects on Rb of Planck scale corrections on gaugino masses are also analysed. It is found that there exist regions of the parameter space where positive corrections to Rb of size ∼ 1σ can be gotten. The region of the par...
متن کاملNew distributed algorithms for fast sign detection in residue number systems (RNS)
We identify a canonical parameter in the Chinese Remainder Theorem (CRT) and call it the ‘‘Reconstruction Coefficient’’, (denoted by ‘‘RC ’’); and introduce the notions of ‘‘Partial’’ and ‘‘Full’’ Reconstruction. If the RC can be determined efficiently, then arithmetic operations that are (relatively) harder to realize in RNS; including Sign Detection, Base change/extension and Scaling or divis...
متن کاملThe single superoxide dismutase of Rhodobacter capsulatus is a cambialistic, manganese-containing enzyme.
The phototrophic bacterium Rhodobacter capsulatus contains a single, oxygen-responsive superoxide dismutase (SOD(Rc)) homologous to iron-containing superoxide dismutase enzymes. Recombinant SOD(Rc), however, displayed higher activity after refolding with Mn(2+), especially when the pH of the assay mixture was raised. SOD(Rc) isolated from Rhodobacter cells also preferentially contains manganese...
متن کاملInhibitory synaptic modulation of renshaw cell activity in the lumbar spinal cord of neonatal mice.
In the mammalian spinal cord, Renshaw cells (RCs) are excited by axon collaterals of motoneurons (MNs), and in turn, provide recurrent inhibition of MNs. They are considered an important element in controlling the motor output. However, how RCs are modulated by spinal circuits during motor behaviors remains unclear. In this study, the physiological nature of inhibitory synaptic inputs to RCs in...
