• PubMed Abstract: 
  

  The structure of fructose 1,6-bisphosphate aldolase shows three distinct modes of product binding that are correlated to the disposition of the C-terminal region and depicts a possible trajectory for product exchange. The structure also indicates binding preference for monobasic triose phosphates.
