Antimycin Congeners
Antimycins are produced as secondary metabolites by ''Streptomyces'' bacteria, a soil bacteria. These specialized metabolites likely function to kill neighboring organisms in order to provide the streptomyces bacteria with a competitive edge. Chemical structures Biosynthesis Antimycins are produced by a non-ribosomal peptide synthetase (NRPS)/polyketide synthase (PKS) assembly complex which acts as an assembly line for antimycin production. The assembly is genetically coded for by the ant gene family. The assembly requires 14 proteins, AntBCDEFGHIJKLMNO, which shuttle the intermediates along the assembly line through a series of transesterifications, keto reductions, thiolations (addition of a sulfur containing group), condensations, anadenylations The last two steps involving AntB and AntO are tailoring steps. The following steps describe chemically what the Ant Enzymes do in order to synthesize Antimycin. Synthesis begins with tryptophan, an amino acid. 1. The in ...

Actinomycete
The Actinomycetales is an order of Actinomycetota. A member of the order is often called an actinomycete. Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern. Some actinomycetes can form rod- or coccoid-shaped forms, while others can form spores on aerial hyphae. Actinomycetales bacteria can be infected by bacteriophages, which are called actinophages. Actinomycetales can range from harmless bacteria to pathogens with resistance to antibiotics. Reproduction Actinomycetales have 2 main forms of reproduction: spore formation and hyphae fragmentation. During reproduction, Actinomycetales can form conidiophores, sporangiospores, and oidiospores. In reproducing through hyphae fragmentation, the hyphae formed by Actinomycetales can be a fifth to half the size of fungal hyphae, and bear long spore chains. Presence and associations Actinomycetales can be found mostly in soil and decaying organic matter, as well as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
