Neisseria gonorrhoeae (Strain A) induces a sialyl-transferase when treated with a very low concentration of cytidine 5'monophospho-N-acetyl neuraminic acid, 2 x 10(-3) nmol.ml-1, a concentration which is insufficient to produce an adequate resistance to human serum complement. The sialyl-transferase activity was detected by measurement of fixed 14C radio-labeled sialyl groups. Without this stimulation, there was practically no transfer of sialyl groups. The gonococcal sialyl-transferase could be considered inducible.

D002250 Carbon Radioisotopes Unstable isotopes of carbon that decay or disintegrate emitting radiation. C atoms with atomic weights 10, 11, and 14-16 are radioactive carbon isotopes. Radioisotopes, Carbon
D002701 Chloramphenicol An antibiotic first isolated from cultures of Streptomyces venequelae in 1947 but now produced synthetically. It has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. It acts by interfering with bacterial protein synthesis and is mainly bacteriostatic.

D012799 Sialyltransferases A group of enzymes with the general activity CMP-N-acetylneuraminate:acceptor N-acetylneuraminyl transferase. They catalyze the transfer of N-ACETYLNEURAMINIC ACID from CMP-N-ACETYLNEURAMINIC ACID to an acceptor, which is usually the terminal sugar residue of an oligosaccharide, a glycoprotein, or a glycolipid.
