Borreliae employ multiple immune evasive strategies such as binding to complement regulatory proteins [factor H (fH) and factor H like-1 (FHL1)], differential regulation of surface membrane proteins, antigenic variation, and binding of plasminogen/plasmin and matrix metalloproteinases. As a complement regulatory

Cyanophycin (multi-l-arginyl-poly-l-aspartic acid; also known as cyanophycin grana peptide [CGP]) is a putative precursor for numerous biodegradable technically used chemicals. Therefore, the biosynthesis and production of the polymer in recombinant organisms is of special interest. The synthesis of cyanophycin derivatives

We have developed an approach that enables nonradioactive, ultrasensitive (attamole sensitivity) site-specific protein-protein photocrosslinking, and we have applied the approach to the analysis of interactions of alpha-helix 2 (H2) of human TATA-element binding protein (TBP) with general transcription factor TFIIA

MALDI-TOF MS recently emerged as a valuable identification tool for bacteria and yeasts and revolutionized the daily clinical laboratory routine. But it has not been established for routine mould identification. This study aimed to validate a standardized procedure for MALDI-TOF

The low density lipoprotein receptor-related protein 1 (LRP1) mediates internalization of a large number of proteins and protein-lipid complexes and is widely implicated in Alzheimer's disease. The cytoplasmic domain of LRP1 (LRP1-CT) can be phosphorylated by activated protein-tyrosine kinases at
