Table 2 Summary of metabolic and translation reactions

Protein	Reaction	Stoichiometry	Description
\(E_T\)	\(v_t\)	\(c_i^x + e \rightarrow c_i\)	Inorganic carbon uptake
\(E_C\)	\(v_c\)	\(3\cdot c_i + 23 \cdot e \rightarrow c_3\)	Carbon assimilation
\(E_M\)	\(v_m\)	\(2\cdot c_3 + 22 \cdot e \rightarrow aa\)	Metabolism
\(E_Q\)	\(v_q\)	\(c_3 + e \rightarrow c_q\)	Synthesis of quota compounds
R	\(\gamma _j\)	\(n_j\cdot aa + 3 \cdot n_j \cdot e \rightarrow P_j\)	Translation by ribosomes

The protein complex \(E_T\) imports extracellular inorganic carbon and represents import and carbon concentrating mechanisms. The protein complex \(E_C\) catalyzes assimilation of inorganic carbon into the carbon precursor \(c_3\) (Calvin–Benson cycle). The protein complex \(E_M\) catalyzes the synthesis of amino acids (central metabolism), whereas the protein complex \(E_Q\) catalyzes the synthesis of other metabolic compounds \(c_q\). The remaining two protein complexes are the photosynthetic unit (PSU) and a (non-functional) quota protein compound \(P_Q\)
