Excerpt of the C ₂ Card centered at the EC number ‘6.2.1.4’ (succinate-CoA ligase (GDP-forming)). The reaction in grey is found in all databases, the reaction in red only in EHMN and KEGG. ‘|==|’ indicates no direction provided by the database. Genes are represented by HGNC symbols, retrieved via Entrez Gene IDs. Genes, the products of which form a complex, are placed between parentheses and connected by the Boolean operator ‘and' (see Materials and methods). If gene products are isozymes ‘or’ is used.
