摘要:
2-Amino-2-deoxy-D-mannitol is not only useful as a cosmetic or as a starting material for preparing X ray contrast media, but also a useful substance having a specific activity of enhancing the yield of moranoline in the production of moranolin; it has been found that 2-amino-2-deoxy-D-mannitol can be manufactured by culturing a microorganism belonging to the genus Streptomyces and capable of producing 2-amino-2-deoxy-D-mannitol in a medium and isolating it from the obtained culture broth.
摘要:
Disclosed herein is a novel collagenase "discolysin". It is useful for biochemical researches and the treatment of many diseases caused by collagen, such as hernia of intervertebral disc. It can be produced by culturing a discolysin-producing bacterium belonging to genus of Streptomyces in a culture medium and then collecting discolysin from the culture medium.

摘要:
The invention belongs to the field of biotechnology. It concerns a biocatalyst, i.e. a dead or living microorganism or a polypeptide, preferably in isolated form, which exhibits acylase enzymatic activity without lipase- or esterase-activity. The biocatalyst is capable of stereoselectively hydrolysing a racemic acylamide which has an aliphatic acyl residue and which is not a derivative of a natural amino acid.

Novel peptide analogues which exhibit inhibitory activity against aspartic proteinases of the general formula I:, a novel species of actinomycetous microorganism which produces said novel peptide analogues, a process for producing said novel analogues by culturing said species and a pharmaceutical composition containing said analogues.
摘要:
Described is a new immunosuppressant, L-685,487, a monodemethylated rearranged derivative of L-683,590, produced under fermentation conditions utilizing the microorganism, unidentified Actinomycete (Merck Culture Collection MA 6474) ATCC No. 53828. The macrolide immunosuppressant is useful in preventing human host rejection of foreign organ transplants, e.g. bone marrow and heart transplants.

摘要:
L-aminoacylases S 1 and S 2 derived from actinomycetes and having physicochemical characteristics such that it is a L-aminoacylase which acts on a N-acyl-L-amino acid to give a L-amino acid, its substrate profile is wide, and it acts not only on a N-acyl derivative of a natural L-amino acid, but also on a N-acyl derivative of a synthetic L-amino acid, while it does not act on a N-acyl-D-amino acid, a DL-N-acetyl-a-methylbenzylamine and a N-acetyl-D-glucosamine, etc.
摘要:
A purified isolate of an actinomycete identified as ATCC 39364 is capable of producing the anti-microbial/antitumor compound 2-amino-1,9-dihydro-6H-purin-6-one-7-oxide. 2-Amino-1,9-dihydro-6H-purin-6-one-7-oxide is produced by cultivating isolate ATCC 39364 under aerobic conditions in a culture medium containing assimilable sources of carbon and nitrogen until a substantial amount of the compound is produced and thereafter isolating the compound. The antibiotic/antitumor compound 2-amino-1,9-dihydro-6H-purin-6-one-7-oxide and pharmaceutical compositions comprising this compound or one of its pharmaceutically acceptable salts together with a pharmaceutically acceptable carrier are also disclosed.
