- S20 (= S13) mutation to E: Strongly decreases the affinity for AAA and Glu. A mild decrease of affinity is observed for 2-oxoglutarate. Increases the affinity for leucine and 2-oxoisocaproate.
- R23 (= R16) mutation to A: Strongly decreases the affinity for AAA and Glu. A mild decrease of affinity is observed for 2-oxoglutarate which has the same chain length as Glu, but differs by the presence of a 2-oxo group which is not recognized by R-23. Increases the affinity for leucine and 2-oxoisocaproate due to the absence of gamma-carboxyl group.; mutation to Q: Strongly decreases the affinity for AAA and Glu. A mild decrease of affinity is observed for 2-oxoglutarate which has the same chain length as Glu, but differs by the presence of a 2-oxo group which is not recognized by R-23. Increases the affinity for leucine and 2-oxoisocaproate due to the absence of gamma-carboxyl group.
