The activity of rubisco is also regulated by light, but the enzyme itself does not respond to thioredoxin.

Two protons are released during the formation of the ternary complex rubisco–CO2–Mg2+, so activation is promoted by an increase in both pH and Mg2+ concentration.

#Unit 3. Fundamental Processes

There are two class of AATS.
1.Class I – that transfer amino acid at 2’ OH and then 3’ OH &
2. Class II – that directly transfer the amino acid to 3’ OH
