The regulation of antibiotic biosynthesis by Streptomyces species is complex, especially for biosynthetic gene clusters with multiple regulatory genes. The biosynthetic gene cluster for the polyene antibiotic candicidin contains four consecutive regulatory genes, which encode regulatory proteins from different families and which form a subcluster within the larger biosynthetic gene cluster in Streptomyces sp.

ATC code G01 Gynecological antiinfectives and antiseptics is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the WHO for the classification of drugs and other medical products. Subgroup G01 is part of the anatomical group G Genito-urinary system and sex hormones. Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QG01. ATCvet codes without corresponding human ATC codes are cited with the leading Q in the following list. National issues of the ATC classification may include additional codes not present in this list, which follows the WHO version.

Ortiz, Adriana, Ana Esperanza Franco-Molano & Mauricio Bacci Jr. A new species of Leucoagaricus (Agaricaceae) from Colombia. Mycotaxon 106: 371-378. 2008. ABSTRACT: A new taxon of Leucoagaricus is proposed as L. amazonicus. The collection representing this species was collected in the lowlands of the Amazonas Department, Colombia, on a dump produced by ants belonging to Acromyrmex octospinosus. The very particular habitat, the small size and dark brown basidiomata that stain yellowish when bruised, the peronate inferior annulus, and the cheilocystidia which are relatively short, capitate and filled with dense brown contents are some of the features of this species. KEYWORDS: Agaricales, taxonomy, Amazonia ...
Attine ants live in symbiosis with a basidiomycetous fungus that they rear on a substrate of plant material. This indirect herbivory implies that the symbiosis is likely to be nitrogen deprived, so that specific mechanisms may have evolved to enhance protein availability. We therefore hypothesized that fungal proteinase activity may have been under selection for efficiency and that different classes of proteinases might be involved. We determined proteinase activity profiles across a wide pH range for fungus gardens of 14 Panamanian species of fungus-growing ants, representing eight genera. We mapped these activity profiles on an independently obtained molecular phylogeny of the symbionts and show that total proteinase activity in lower attine symbionts peaks at ca. pH 6. The higher attine symbionts that have no known free-living relatives had much higher proteinase activities than the lower attine symbionts. Their total in vitro proteinase activity peaked at pH values around 5, which is close to the pH
The social Hymenoptera have distinct larval and adult stages separated by metamorphosis, which implies striking remodeling of external and internal body structures during the pupal stage. This imposes challenges to gut symbionts as existing cultures are lost and may or may not need to be replaced. To elucidate the extent to which metamorphosis interrupts associations between bacteria and hosts, we analysed changes in gut microbiota during development and traced the transmission routes of dominant symbionts from the egg to adult stage in the leaf-cutting ants Acromyrmex echinatior and Atta cephalotes, which are both important functional herbivores in the New World tropics. Bacterial density remained similar across the developmental stages of Acromyrmex, but Atta brood had very low bacterial prevalences suggesting that bacterial gut symbionts are not actively maintained. We found that Wolbachia was the absolute dominant bacterial species across developmental stages in Acromyrmex and we confirmed that Atta
But the story can get more complicated. Imagine a symbiosis with four co-evolving partners: three of them are engaged in a mutualistic relationship, while the fourth one is a parasite. Thats the beautiful case of fungus-growing ants. In their underground nests, the ants grow a mushroom-like fungus by feeding it with plant materials or other organic matter. In turn, the fungus serves as food for the ants (yes, this is agriculture!). But every garden has its pests, and the ants farm is home for the Escovopsis mold. Escovopsis is a specialized pest, found only on the crop of farming ants. To battle the parasite, the ants combine special behaviors and microbial symbionts. These insects carry a bunch of antibiotic-producing actinomycetes in elaborate cuticular crypts, supported by unique exocrine glands. The symbiotic bacteria produce substances that specifically inhibit Escovopsis growth. Although initially identified as Streptomyces, the actinomycete symbionts appear to belong to the ...

Leafcutter ants, signature denizens of New World tropical forests, are unique in their ability to harvest fresh leaves to cultivate a nutrient-rich fungus as food.. Now, this mutualism -- a complicated interplay of ants, fungi and a suite of bacteria -- is coming into sharper focus as a team of University of Wisconsin-Madison researchers has published the complete genome of the leafcutter ant, Atta cephalotes.. The study, published today (Feb. 10, 2011) in the journal Public Library of Science (PLoS) Genetics, by an international team led by UW-Madison bacteriology professors Cameron Currie and Garret Suen, illustrates how lifestyle can remake an animals genetic blueprint over the course of evolutionary history.. The genome, the first for a leafcutter ant, reveals that the insect has shed genes that other ant species use to help acquire nutrients. The leafcutter, which cannot survive without its fungus food, has apparently slimmed its genome to get rid of genes it no longer needs due to its ...
FR-900520 and FR-900523, novel neutral macrolide immunosuppressants, were isolated from the cultured broth of Streptomyces hygroscopicus subsp. yakushimaensis No. 7238. Their molecular formulae were determined as C43H69NO12 and C42H67NO12, respectively. The compounds suppressed immune response in vitro. IC50 values of FR-900520 and FR-900523 for mouse mixed lymphocyte reaction were 0.55 nM and 1.6 nM, respectively. FR-900520, the major component, clearly prolonged skin allograft survival in rats.

Biosynthetic Production of 4-Amino 4-Deoxychorismate (Adc) and [3R,4R]-4-Amino-3-Hydroxycyclohexa-1,5-Diene-1-Carboxylic Acid (3,4-Cha) - The invention relates to a process for the biosynthetic production of 4-amino-4-deoxychorismate (ADC) performed fermentatively in vivo with a 4-amino-4-deoxychorismate synthase, preferably a PabAB bipartite protein (which may be a fusion protein), at an increased level of activity, thereby obtaining a broth comprising ADC and 4-amino-4-deoxyprephenate (ADP), that are recovered. The invention also relates to a further process of converting the ADP into p-aminophenylalanine. The invention, moreover relates to biosynthetic production of [3R,4R]-4-amino-3-hydroxycyclohexa-1,5-diene-1-carboxylic acid (3,4-CHA), by concerted action of such 4-amino-4-deoxychorismate synthase and of an enzyme capable of converting isochorismate into [5S,6S]-5,6 dihydroxycyclohexa-1,3-diene-1-carboxylic acid (2,3-CHD), preferably a phenazine biosynthesis protein PhzD, including ...
Ten years ago, Cameron Currie, a microbial ecologist then at the University of Toronto in Ontario, Canada, discovered that leaf-cutting ants carry colonies of actinomycete bacteria on their bodies (C. R. Currie et al. Nature 398, 701-704; 1999). The bacteria churn out an antibiotic that protects the ants fungal crops from associated parasitic fungi (such as Escovopsis). On 29 March, Currie, Jon Clardy at the Harvard Medical School in Boston and their colleagues reported that they had isolated and purified one of these antifungals, which they named dentigerumycin, and that it is a chemical that has never been previously reported (D.-C. Oh et al. Nature Chem. Bio. doi: 10.1038/nchembio.159; 2009). The antifungal slowed the growth of a drug-resistant strain of the fungus Candida albicans, which causes yeast infections in people ...
