摘要:The present invention relates to the isolation and identification of novel genes of the biosynthetic pathway for spiramycins and to novel polypeptides involved in this biosynthesis. The invention also relates to a method for producing these polypeptides. It also relates to the use of these genes for the purpose of increasing the levels of production and the purity of the spiramycin produced. The invention relates in particular to a microorganism which produces spiramycin I but which does not produce spiramycin II and III, and to the use of such a microorganism. The invention also relates to the use of the genes of the biosynthetic pathway for spiramycins for constructing mutants which can lead to the synthesis of novel antibiotics or to derived forms of spiramycins. The invention also relates to the molecules produced through the expression of these genes and to pharmacologically active compositions of a molecule produced through the expression of such genes.

摘要:The invention provides methods for producing high resolution crystals of ribosomes and ribosomal subunits as well as crystals produced by such methods. The invention also provides high resolution structures of ribosomal subunits either alone or in combination with protein synthesis inhibitors. The invention provides methods for identifying ribosome-related ligands and methods for designing ligands with specific ribosome-binding properties as well as ligands that may act as protein synthesis inhibitors. Thus, the methods and compositions of the invention may be used to produce ligands that are designed to specifically kill or inhibit the growth of any target organism.

摘要:The present disclosure provides a biosynthetic gene cluster of carrimycin. The biosynthetic gene cluster comprises 44 gene open reading frames (orf), i.e., 5 orfs (orf10-14) encoding polyketide synthase, 9 orfs (orf1, 4-6, 15 and 36-39) related to polyketone synthesis extension unit and modification, 16 orfs (orf9, 16-22, 24, 26, 28, 29, 33-35 and 41) related to glycosyl synthesis, 6 orfs (orf7, 8, 30-32 and 40) related to glycosyl transfer, 2 orfs (orf3 and 25) related to resistance, 4 orfs (orf2, 23, 27 and 42) possibly related to regulation, a tsr resistance marker gene orf (orf43) and a 4″-mycaroseglucoside isovaleryl transferase gene orf (orf44).
