evolution | the conserved motifs G-X-X-G-X-X-A and D-X-X-D are reported to be involved in NAD(P) binding and adenine binding pocket stabilization. In addition, the NADP specificity motif R(X)5K is identified, which is a key structure that distinguishes CCR from other NAD(H)-dependent SDRs. Sequence comparisons and phylogenetic analysis of Populus tometosa CCRs, overview. Of the 11 PtoCCR and PtoCCR-like proteins, PtoCCR1 and 7 each catalyze at least one substrate. PtoCCR1 is active only with feruloyl-CoA as a substrate, while PtoCCR7 accepts all hydroxycinnamoyl-CoA esters | Populus tomentosa |
malfunction | the positively charged extended structure of His208 was important in stabilizing CoA, while the mutants (M208, V208, and Y208) were unable to assume this function | Populus tomentosa |
