According to your ms. with KYKYKYYU Kurahashi, last line page 14, the galactose-sensitive strains of Fukasewa and Hikaido ‘seems also to have a single block in the Gal-l-P uridyl transferase’, Surely this is a typc- graphical error and you mean here the simerese (as you said in your talk). Please conf i rm. (Esther will put ‘epimerase’ in her ms. referring to you, and wi 11 change in prtiaf ‘i f we have real ly misunderstood y<:u. ) 2. p. 18 “The complex palysaccharides. .frm W-3099 did not contain detectable amounts of galactose”.
