Metabolic pathways in Microbispora sp. ATCC-PTA 5024, producer of NAI-107 lantibiotic

Proteomics to elucidate the molecular physiology of Microbispora sp. ATCC-PTA-5024, the producer of NAI-107, a very promising lantibiotic

The filamentous actinobacterium Microbispora sp. ATCC-PTA-5024 produces the lantibiotic NAI-107 (Maffioli et al., 2014), which is effective against multidrug-resistant Gram-positive pathogens (Jabés et al., 2011). In actinomycetes, the biosynthesis of antibiotics is generally elicited as a physiological response controlled by a complex regulatory network involving global regulators, playing pleiotropic roles, and pathway-specific regulators, which activate the biosynthesis of biologically active molecules (Bibb, 2005)
