English

Subject field(s)
  • Biochemistry
DEF

The photosynthetic carboxylation enzyme of green plants and purple and green bacteria. It is structurally bound in the thylakoids, but is easily solubilized during isolation. The enzyme consists of two types of subunit; the larger subunit is encoded in the nuclear genome of the plant, the smaller subunit in the plastid DNA.

CONT

An enzyme called RuBISCO (ribulosebisphosphate carboxylase) converts the carbon dioxide into 3-PGA. Finally the Calvin cycle takes over and turns the carbon into sugars and starch in the same way C3 plants do.
