Amino Acid Racemase Enzyme Assays

open access: yesBio-Protocol, 2014
Amino acid racemases are enzymes that invert the α-carbon stereochemistry of amino acids (AAs), interconverting amino acids between their L- and D-enantiomers in a reversible reaction. In bacteria, they are known to have catabolic physiological functions

Conductimetric Enzyme Assays [PDF]

open access: yesEuropean Journal of Biochemistry, 1971
A direct reading, six channel conductivity recording apparatus has been constructed and used to assay enzymes, including some of those found in muscle. This paper gives the essential theory of the method, and indicates that it is a highly versatile assay system. It may be applicable whenever ionic substrates are involved, but this is more easily tested
