Genetic characterization of S1 gene of infectious bronchitis virus isolated from commercial poultry flocks in West Java, Indonesia [PDF]

open access: yesVeterinary World, 2019
Background and Aim: Infectious bronchitis (IB) is still a major problem among poultry industry in Indonesia, IB outbreaks continue to happen even in vaccinated flocks. The emergence of new IB virus (IBV) variants might lead to mismatching between vaccine

Characterization of a supercoil-dependent S1 sensitive site 5' to the Drosophila melanogaster hsp 26 gene. [PDF]

open access: yesNucleic Acids Research, 1986
We have analyzed the prominent supercoil-dependent S1 nuclease cleavage site 5' to hsp 26 in the plasmid 88B13, which contains 11.7 kilobases from the Drosophila locus 67B1. The double stranded cleavage product is generated by initial nicking on the purine strand, six preferred sites occurring between positions -96 and -90 (relative to the start of ...

Development and characterization of a recombinant infectious bronchitis virus expressing the ectodomain region of S1 gene of H120 strain

open access: yesApplied Microbiology and Biotechnology, 2013
Infectious bronchitis (IB), caused by infectious bronchitis virus (IBV), is a highly contagious chicken disease, and can lead to serious economic losses in poultry enterprises. The continual introduction of new IBV serotypes requires alternative strategies for the production of timely and safe vaccines against the emergence of variants. Modification of

Cloning and characterization of a gene from Rhizobium melilotii 2011 coding for ribosomal protein S1.

open access: yesNucleic Acids Research, 1988
A 7 kb chromosomal DNA fragment from R. melilotii was cloned, which complemented temperature-sensitivity of an E. coli amber mutant in rpsA, the gene for ribosomal protein S1 (ES1). From complementation and maxicell analysis a 58 kd protein was identified as the homolog of protein S1 (RS1). DNA sequence analysis of the R. melilotii rpsA gene identified
