What is MACULOSIN?
Description
Maculosin is a diketopiperazine metabolite produced by A. alternata, L. capsici, Streptomyces, and the Gram-negative, nonobligate predator bacterial strain 679-2. It acts as a host-specific phytotoxin, inducing formation of weeping necrotic lesions in leaves of spotted knapweed (C. maculosa) when used at a concentration of 10 μM. Maculosin reduces the growth of the plant pathogenic bacteria X. axonopodis and R. solanacearum (MICs = 31.25 μg/ml) as well as the pathogenic oomycetes P. cactorum, P. capsici, P. cinnamomi, P. infestans, and P. ultimum when used at concentrations ranging from 10 to 100 mg/ml. Maculosin also inhibits the growth of M. luteus, M. smegmatis, S. cerevisiae, C. albicans, C. neoformans, and A. niger when used in combination with pyrrolnitrin or banegasin.
The Uses of MACULOSIN
Cyclo(L-Pro-L-Tyr) (maculosin) is a diketopiperazine formed by the fusion of tyrosine and proline, reported as a secondary metabolite of fungi and bacteria. In Pseudomonas aeruginosa, cyclo(L-Pro-L-Tyr) is capable of activating N-acylhomoserine lactones (AHLs). Cyclo(L-Pro-L-Tyr) is also capable of activating or antagonizing other LuxR-based quorum-sensing systems. While the mode of action of cyclo(L-Pro-L-Tyr) is not known, its activity suggests the existence of cross talk among bacterial signalling systems. Cyclo(L-Pro-L-Tyr) was identified as a host-specific toxin produced by Alternaria alternata on spotted knapweed.
The Uses of MACULOSIN
Cyclo(L-prolinyl-L-tyrosine) is a diketopiperazine derivative isolated from Bacillus thuringiensis and Bacillus endophyticus.
