We report the draft genome of Streptomyces rimosus (ATCC 10970), a soil isolate that produces oxytetracycline, a commercially important and clinically useful antibiotic.

Enveloped viruses utilize the membranous compartments of the host cell for the assembly and budding of new virion particles. In this report, we have investigated the biogenesis and trafficking of the envelope glycoprotein (GP-C) of the Junín arenavirus. The mature GP-C complex is unusual in that it retains a stable signal peptide (SSP) as an essential component in association with the typical r...

Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published sources for the period 1842-2016. A geographic...

L-Phenylalanine and L-tyrosine were completely catabolized through homogentisate by Streptomyces setonii 75Vi2 but only partially degraded by Streptomyces badius 252, Streptomyces sioyaensis P5, Streptomyces viridosporus T7A, and Streptomyces sp. strain V7. Intermediates of catabolism were confirmed by thin-layer, gas, and high-pressure liquid chromatography. Homogentisate 1,2-dioxygenase was p...

Actinomycetes were isolated from marine sediment samples collected from the east coast of Chennai, Tamil Nadu, India. Well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant Methicillin- resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococci (VRE). The potential isolate VITBRK2 was mass cultured for...

Eighteen Palaearctic taxa of the Mniotype adusta species-group are reviewed. One new species (M. kobyakovi Volynkin, Matov & Behounek, sp. n.) and six new subspecies (M. lama kortka Volynkin, Matov & Behounek, ssp. n., M. lama etugen Volynkin, Matov & Behounek, ssp. n., M. lama ayubaevorum Volynkin, Matov & Behounek, ssp. n., M. adusta poltavskyi Volynkin, Matov & Behounek, ssp. n., M. adjuncta...

The subset sum problem (SSP) can be briefly stated as: given a target integer E and a set A containing n positive integer aj , find a subset of A summing to E. The density d of an SSP instance is defined by the ratio of n to m, where m is the logarithm of the largest integer within A. Based on the structural and statistical properties of subset sums, we present an improved enumeration scheme fo...

OBJECTIVE To evaluate the effects of self-ligating bracket (SLB) type and vibration on frictional force and stick-slip phenomenon (SSP) in diverse tooth displacement conditions when a levelling/alignment wire was drawn. MATERIALS AND METHODS A total of 16 groups were tested (n = 10/group): Two types of SLBs [active SLB (ASLB, In-Ovation R) and passive SLB (PSLB, Damon Q)]; vibration (30 Hz an...
