Differential proteomic analysis reveals novel links between primary metabolism and antibiotic production in Amycolatopsis balhimycina.
2010
A differential proteomic analysis, based on 2-DE and MS procedures, was performed on Amycolatopsis balhimycina DSM5908, the actinomycete producing the vancomycin-like antibiotic balhimycin. A comparison of proteomic profiles before and during balhimycin production characterized differentially and constitutively expressed protein isoforms, which were associated to 203 ORFs in the A. balhimycina genome. These data, providing insights on the major metabolic pathways/molecular processes operating in this organism, were used to compile 2-DE reference maps covering 3-10, 4-7 and 4.5-5.5 pH gradients available over the World Wide Web as interactive web pages (http://www.unipa.it/ampuglia/Abal-prot…

In actinomycetes, antibiotic production is often associated with a morpho-physiological differentiation program that is regulated by complex molecular and metabolic networks. Many aspects of these regulatory circuits have been already elucidated and many others still deserve further investigations. In this regard, the possible role of many small open reading frames (smORFs) in actinomycete morpho-physiological differentiation is still elusive. In Streptomyces coelicolor, inactivation of the smORF trpM (SCO2038) – whose product modulates L-tryptophan biosynthesis – impairs production of antibiotics and morphological differentiation. Indeed, it was demonstrated that TrpM is able to interact w…
