Functional shifts of the dual-substrate phosphoribosyl isomerase PriA from primary to specialized metabolism in rare Actinomycetota

{{output}}
Evolutionary functional innovations can occur while gene families expand and two homologous (or analogous) genes co-occur. PriA is a dual-substrate enzyme family exclusive to Actinomycetota, with activities in l-histidine and l-tryptophan biosynthesis (HisA an... ...
