Evolution of AGPase duplicates

ADP-glucose pyro­phos­phorylase (AGPase), a key enzyme in starch bio­syn­thesis, is com­prised of large (LSU) and small (SSU) sub-units encoded by mul­tiple para­log­ous genes in angio­sperms. Corbi et al. invest­ig­ate the pat­terns of molecu­lar evol­u­tion of AGPase genes fol­low­ing duplic­a­tions. They find that both coe­volu­tion among amino acid residues loc­ated in between-sub-unit inter­ac­tion domains or within the highly con­strained SSU, and repeated sub­func­tion­al­iz­a­tion events under the ‘Escape from Adaptive Conflict’ model have con­trib­uted to AGPase evolution.
