Effect of W v Locus in Mouse on Differential Excretion of Isomers of Several Amino Acids. ∗

Abstract

Summary

Mice of W^vW^v, WW^y, and W^v w genotypes, unlike other mice, excrete the D-isomers of phenylalanine, tyrosine, tryptophane, methionine and histidine when the D + L isomers of these amino acids are fed. Ww and ww mice, however, otherwise genetically similar to the above, are able to utilize both the D and L isomers of these amino acids.
