| c4 cycle | <plant biology> An alternative, very efficient pathway used by plants living in areas with low levels of carbon dioxide, to convert carbon dioxide into a form usable by the plants during photosynthesis. (09 Oct 1997) |
|---|---|
| C4 plant | <plant biology> Plants found principally in hot climates whose initial fixation of carbon dioxide in photosynthesis is by the HSK pathway. The enzyme responsible is PEP carboxylase, whose products contain four carbon atoms. Subsequently the carbon dioxide is released and re fixed by the Calvin Benson cycle. The presence of the HSK pathway permits efficient photosynthesis at high light intensities and low carbon dioxide concentrations. most species of this type have little or no photorespiration.

| C4 binding protein |
a complement system regulatory protein that inhibits activation of the classical pathway; it both accelerates decay of the classical pathway C3 convertase by binding to C4b and displacing C2a and is also a cofactor for factor I

| C4 |
Controlled collapse chip connection: a technique of solder joint flip chip connection to a substrate where the surface tension forces of the molten solder controls the height of the joint and supports the weight of the chip.

| C4 binding p. |
a complement system regulatory protein that inhibits activation of the classical pathway; it both accelerates decay of the classical pathway C3 convertase by binding to C4b and displacing C2a and is also a cofactor for factor Imediated cleavage of C4b.

| C4a |
a weak anaphylatoxin generated by cleavage of C4 by C1s in the classical pathway of complement activation.

|
| C4b |
a constituent of the classical pathway C3 convertase (C4b,2a), generated by cleavage of C4 by C1s; the active fragment C4b then binds C2 for cleavage of C2 by C1s. It is inactivated by factor I in the presence of C4 binding protein. C4b is also an opsonin that binds to the same receptors as C3b.
