2.6.1.66
Activity 2.6.1.66
Description Valine--pyruvate aminotransferase.
Notes This group of enzymes play a minor role in the bacterial biosynthesis of valine.
The family has been built starting from the only functionally characterized gene (E. coli).

Note that the that enzymes in this family are fold-type I, whereas the enzymes in the 2.6.1.42 family (branched-chain amino acid aminotransferase) are are fold-type IV. This may represent yet another instance of convergent evolution in PLP-dependent enzymes.
