Enzymes involved in energy metabolism.

*Some enzymes of the TCA cycle (e.g. fumarase) and mitochondrial complex I can also be considered as part of the fermentation pathways (see the text and legend to Figure 6); for simplicity, they are included in the former category only. #Cluster EGC00753 (CW: 16; PSP: 5) encodes a mitochondrial citrate lyase beta-like protein, which could be involved in citrate fermentation. §Clusters corresponding to incompletely processed transcripts (i.e. they contain non-removed introns). Also participates in gluconeogenesis.
