Analysis of theEscherichia coli proBAlocus by DNA and protein sequencing

Analysis of the Escherichia coli proBA locus by DNA and protein sequencing.

A 2.9 kb DNA fragment carrying the Escherichia coli proBA region, which encodes the first two enzymes of the proline biosynthetic pathway, was subcloned onto an expression plasmid carrying both the bacteriophage lambda PL promoter (lambda PL) and the lambda gene encoding a thermolabile cI repressor protein (cI857). Derepression of the lambda PL promoter by thermal inactivation of the cI857 repr...

Comparison of cattle BoLA-DRB3 typing by PCR-RFLP, direct sequencing, and high-resolution DNA melting curve analysis

Major histocompatibility complex (MHC) represents an important genetic marker for manipulation to improve the health and productivity of cattle. It is closely associated with numerous disease susceptibilities and immune responses. Bovine MHC, also called bovine leukocyte antigen (BoLA), is considered as a suitable marker for genetic diversity studies. In cattle, most of the polymorphisms are lo...

Isolation and identification of Eurotium species from contaminated rice by morphology and DNA sequencing

30 milled rice samples were collected from retailers in four states of Malaysia. These samples were evaluated for Eurotium spp. contaminations by direct plating on malt extract salt agar (MESA). All Eurotium were isolated and identified based on morphology and nucleotide sequences of internal transcribed spacer 1 (ITS1) and ITS2 of the rDNA.  Four Eurotium species (E. rubrum, E. amstelodami, E....
