Fig. 3From: Unusual acylation of chloramphenicol in Lysobacter enzymogenes, a biocontrol agent with intrinsic resistance to multiple antibioticsHPLC analysis of the reaction products of E. coli CAT with chloramphenicol and acetyl-CoA (a), isobutyryl-CoA (b), or isovaleryl-CoA (c) as substrate. In each pair of the HPLC traces, the top trace is from the reaction, and the bottom trace is from control (no CAT). Two acyl chloramphenicol products were produced in each of the reactions, as indicated by the arrows, with the first peak being the 1'-acyl chloramphenicol and the second the 3'-acyl chloramphenicolBack to article page
