A nucleic acid molecule encoding the gilvocarcin V gene cluster and subunits thereof. Recombinant vectors and host cells comprising a nucleic acid compound encoding the gilvocarcin V gene cluster or subunits thereof. Host cells comprising recombinant vectors encoding the gilvocarcin polyketide synthase and gilvocarcin post-PKS modifying enzymes from Streptomyces griseoflavus can be used to produce gilvocarcin and functional gilvocarcin mutants, analogs and derivatives thereof with application as antibiotics, anticancer agents, immunosuppressants, antivirals, and neuroprotective agents.
摘要:
The invention, in one aspect, generally relates to mithramycin derivatives from mutated Streptomyces argillaceous and their production. The invention also relates using the derivatives for the treatment of various diseases. Finally, the invention relates to a mutated Streptomyces argillaceous useful in the production of the mithramycin derivatives.

摘要:
An improvement to a laser ceilometer and like instruments comprises a laser diode array which includes a plurality of laser diodes, and an array driver driving the laser diode array in accordance with commands from a microprocessor. The laser diodes are GaAs diodes. By utilizing the improvement, service life and reliability of the ceilometer are both increased.
