Whereas the determination of high enantiomeric fractions (EF) of chi- ral compounds is very well established, the accurate determination of small deviations from racemic compositions has not yet received much attention despite its relevance to studie

Many Gram-positive bacteria produce lipoteichoic acid (LTA) polymers whose physiological roles have remained a matter of debate because of the lack of LTA-deficient mutants. The ypfP gene responsible for biosynthesis of a glycolipid found in LTA was
