objective(s): the periodic binding of protein expressed by mycobacterium tuberculosis h37rv with the host cell receptor molecules i.e. fibronectin (fn) is gaining significance because of its adhesive properties.  the genome sequencing of m. tuberculosis h37rv revealed that the proline-glutamic (pe) proteins contain polymorphic gc-rich repetitive sequences (pgrs) which have clinical importance i...

The Saccharomyces cerevisiae Put4 permease is significant for the transport of proline, alanine, and glycine. Put4p downregulation is counteracted by npi1 mutation that affects the cellular ubiquitination function. Here we describe mutant Put4 permeases, in which up to nine lysine residues in the cytoplasmic N-terminal domain have been replaced by arginine. The steady-state protein level of the...

We have evaluated the effects of the proline homologue Aze (1) (azetidine-2-carboxylic acid) on growth of Escherichia coli strains used to over-express recombinant forms of murine myelin basic protein (rmMBP), and on the degree of misincorporation. Addition of Aze to minimal media resulted in severe diminution of growth rate, but rmMBP could still be produced and purified. Mass spectrometry ind...
