- R16 (= R14) mutation to A: Loss of aldol cleavage activity.; mutation to K: 4000-fold decrease in the catalytic efficiency of the aldol cleavage reaction.
- H20 (= H18) mutation H->A,S: 100-fold decrease in the catalytic efficiency of the aldol cleavage reaction. Dramatic reduction in acetaldehyde and propanaldehyde channeling efficiency by more than 70%.
- L87 (= L85) mutation to A: 32-fold reduction in the catalytic efficiency with acetaldehyde as substrate of the aldol addition reaction, but no change in the catalytic efficiency using propanaldehyde; thus, exhibits a 40-fold preference for propanaldehyde over acetaldehyde.; mutation L->N,W: Loss of aldolase activity (with either enantiomer of HOPA), but retains some decarboxylase activity for the smaller oxaloacetate substrate. In the retro-aldol cleavage reaction, is inactive toward 4(S)-HOPA but is active toward 4(R)-HOPA, albeit with a great reduction in catalytic efficiency, and in the aldol addition reaction, produces also exclusively the 4(R)-enantiomer; when associated with F-290.
- L89 (= L87) mutation to A: As the wild-type enzyme, exhibits similar catalytic efficiency with acetaldehyde or propanaldehyde as substrate in the aldol addition reaction but displays higher catalytic efficiency with longer aldehydes (50-fold increase using pentaldehyde). Shows a reduction in aldehyde channeling efficiency by 30%.
- Y290 (= Y288) mutation to F: Loss of stereochemical control as the mutant is able to catalyze the aldol cleavage of substrates with both R and S configurations at C4 with similar kinetic parameters. 3.5-fold decrease in the catalytic efficiency of the aldol cleavage reaction. Reduction in aldehyde channeling efficiency by more than 30%. In the retro-aldol cleavage reaction, is inactive toward 4(S)-HOPA but is active toward 4(R)-HOPA, albeit with a great reduction in catalytic efficiency, and in the aldol addition reaction, produces also exclusively the 4(R)-enantiomer; when associated with N-87 or W-87.; mutation to S: Loss of stereochemical control as the mutant is able to catalyze the aldol cleavage of substrates with both R and S configurations at C4 with similar kinetic parameters. 3.5-fold decrease in the catalytic efficiency of the aldol cleavage reaction.
- G322 (= G320) mutation to A: Displays a reduction in aldehyde channeling efficiency of about 20%.; mutation G->F,L: Unable to channel either acetaldehyde or propanaldehyde.
- G323 (= G321) mutation to A: Able to channel butyraldehyde (with less efficiency than wild-type) but not its isomer isobutyraldehyde.; mutation to F: Unable to channel either acetaldehyde or propanaldehyde.; mutation to L: Able to channel acetaldehyde but not the larger propanaldehyde.
