Structural and Functional Characterization of YdjI, an Aldolase of Unknown Specificity in K12.

The gene cluster is found in 80% of sequenced genomes and other closely related species in the human microbiome. On the basis of the annotations of the enzymes located in this cluster, it is expected that together they catalyze the catabolism of an unknown carbohydrate. The focus of this investigation is on YdjI, which is in the gene cluster of K-12.
