Transaldolase (TAL) is an enzyme of the pentose phosphate pathway (PPP) found almost ubiquitously in the three domains of life (Archaea, Bacteria, and Eukarya). TAL shares a high degree of structural similarity and sequence identity with fructose-6-phosphate aldolase (FSA). They both belong to the class I aldolase family[4]. Their protein structures have been revealed[5].	Domain
