Nonomuraea sp. ATCC 39727 is an aerobic actinomycete, industrially important as a producer of the glycopeptide A40926, which is used as a precursor of the semi-synthetic antibiotic dalbavancin. Previous studies showed that the production of A40926 is depressed by calcium, but promoted byl-glutamine orl-asparagine. In this study, the protein expression changes of Nonomuraea sp. ATCC 39727 in these two different growth and antibiotic-production conditions have been investigated by two-dimensional electrophoresis and mass spectrometry (MS) analysis. Few protein spots show statistically significant expression changes, and, among this group of proteins, malate dehydrogenase (MDH) shows a significant decrease in the overproduction condition. The decrease of MDH is of particular interest because it is the first described significant change in the expression levels of enzymes of the central metabolism related with A40926 overproduction.
