Microbial Transglutaminase (MTgase) shows a wide specificity of action in its ability to interact with proteins from different families. Previous experimental data (in collaboration with BIOKER, POLARIS, Pula, Italy) demonstrated that MTGase interacts and transglutaminates the Granulocyte-Colony-StimulatingFactor (GCSF) at residue Q135. In this work this interaction is investigated through the ...
