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

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

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

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
