Lysine hydroxamate

Lysine hydroxamate is an amino acid hydroxamate that inhibits the growth of Escherichia coli K-12. Of the other amino acid hydroxamates tested, only L-lysine hydroxamate reduced the growth rate. The inhibition of growth by L-serine hydroxamate could be rapidly reversed by adding L-serine to the bacterial culture or by removing the analog by filtration. This reversal was specific for L-serine. L-alanine, glycine, or adenine had no effect on the inhibited culture. There was no evidence for active transport of the analog.
