The combination of atmospheric CO2 with a 3-carbon molecule phosphoenol pyruvate (PEP) to make malic acid. The malic acid is then passed into the vacuole where it is stored until daylight, when it is shuttled back out to be used as a substrate in the light reaction of photosynthesis.

Any process that decreases the rate, frequency or extent of nitric oxide mediated signal transduction. Nitric oxide mediated signal transduction is The series of molecular signals mediated by the detection of nitric oxide (NO).

Any process that stops, prevents or reduces the frequency, rate or extent of intracellular signal transduction.

The process of C4 photosynthesis, as it occurs in plants in which the enzyme decarboxylating C4 acids in the bundle sheath is NADP-malic enzyme.

The combination of atmospheric CO2 with a 3-carbon molecule phosphoenol pyruvate (PEP) in the mesophyll cells to make a 4-carbon acid which is immediately converted to malic acid. The malic acid is then passed across to the bundle sheath cells where it is broken down again to pyruvic acid and CO2. The acid is passed back to the mesophyll cells to be used again, while the CO2 is fed into the reductive pentose-phosphate cycle (Calvin cycle) and converted into sugar and starch.

Any process that modulates the rate, frequency or extent of cGMP-mediated signaling.

Any process that increases the rate, frequency or extent of cGMP-mediated signaling.

Absorption and transfer of the energy absorbed from light photons between photosystem reaction centers.

OBSOLETE. In the photosynthetic reaction centers, primary charge separation is initiated by the excitation of a molecule followed by the transfer of an electron to an electron acceptor molecule following energy transfer from light harvesting complexes.

Catalysis of the reaction: D-allulose 6-phosphate = D-fructose 6-phosphate.

Catalysis of a reaction that alters the configuration of one or more chiral centers in a carbohydrate molecule.

The process of C4 photosynthesis, as it occurs in plants in which the enzyme decarboxylating C4 acids in the bundle sheath is NAD-malic enzyme.

The process of C4 photosynthesis, as it occurs in plants in which the enzyme decarboxylating C4 acids in the bundle sheath is phosphoenolpyruvate carboxykinase (PEPCK).

After a photon of light is absorbed by one of the many chlorophyll molecules, in one of the light-harvesting complexes of an antenna on photosystem II, some of the absorbed energy is transferred to the pair of chlorophyll molecules in the reaction center.

A process, occurring as part of photosynthesis, in which light provides the energy for a series of electron carriers to operate together to transfer electrons and generate a transmembrane electrochemical gradient.

A process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors.

After a photon of light is absorbed by one of the many chlorophyll molecules, in one of the light-harvesting complexes of an antenna on photosystem I, some of the absorbed energy is transferred to the pair of chlorophyll molecules in the reaction center.

A large (20 S) protein complex that possesses protein arginine methyltransferase activity and modifies specific arginines to dimethylarginines in the arginine- and glycine-rich domains of several spliceosomal Sm proteins, thereby targeting these proteins to the survival of motor neurons (SMN) complex for assembly into small nuclear ribonucleoprotein (snRNP) core particles. Proteins found in the methylosome include the methyltransferase JBP1 (PRMT5), pICln (CLNS1A), MEP50 (WDR77), and unmethylated forms of SM proteins that have RG domains.

Any process that modulates the rate, frequency or extent of macrophage chemotaxis. Macrophage chemotaxis is the movement of a macrophage in response to an external stimulus.

Any process that modulates the frequency, rate, or extent of leukocyte chemotaxis.
