Acetylation of Sulphanilamide by Acetyl Metaphosphate
Nature, 1950THE problem regarding the nature of the reactive, intermediate C2-compound in acetate metabolism is not clear at present. With regard to biological acetylations, it is evident, especially from Lipmann's1 work, that a strongly acetylating substance is formed in an enzymatic reaction between acetate and adenosine triphosphate.

Structures of Some Acetyl-serine Peptides from Acetyl-chymotrypsin
Nature, 1960IN 1958, two of us1 obtained, by enzymic degradation of acetyl-chymotrypsin labelled with carbon-142, five peptides containing labelled acetyl-groups. Subsequent sequence studies3 have shown that the largest of these peptides has the amino-acid sequence, Gly.Asp.Ser.Gly.Gly.Pro.Leu, identical with that already found4, by degradation of the di ...
