Metabolism recurring motifs

In C albicans, mutations that block cAMP/PKA pathway suppress or delay the apoptotic response to H2O2 and amphotericin B. By contrast, mutations that result in constitutive activation of the RAS pathway accelerate entry into the apoptotic pathway Apoptosis and quorum sensing in filamentous fungi are phenomena associated with stress responses, a recurring motif in morphogenesis and secondary metabolism. The treatment of Colletotrichum trifolii with proline, a known stress relief chemical, suppressed apoptosis associated with Ras as well as apoptosis associated with a variety of other stresses.

Metabolism is characterized by common motifs. A small number of activated carriers, such as ATP, NADH, and acetyl CoA, are used in many metabolic pathways. NADPH, which carries two electrons at a high potential, provides reducing power in the biosynthesis of cell components from more-oxidized precursors. ATP and NADPH are continually generated and consumed. Most transfers of activated groups in metabolism are mediated by a recurring set of carriers. Moreover, key reaction types are used repeatedly in metabolic pathways. [Pg.592]
