The small subunit of Rubisco and its potential as an engineering target

Area of Science:

• Biochemistry
• Molecular Biology
• Plant Science

Background:

• Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the rate-limiting step of CO2 fixation, crucial for biosphere carbon.
• Rubisco is a major engineering target to improve photosynthetic efficiency in agriculture and biotechnology.
• Form I Rubisco, comprising large and small subunits, is widespread in plants, algae, and bacteria.

Conclusions:

• The Rubisco small subunit is an increasingly recognized and valuable target for Rubisco engineering.
• Modulating small subunit function presents a viable strategy to enhance photosynthetic efficiency.
• Further research into small subunit roles and engineering holds significant potential for biotechnology and agriculture.
