To develop artificial hemoproteins that could lead to new selective oxidation biocatalysts, a strategy based on the insertion of various iron-porphyrin cofactors into Xylanase A (Xln10A) was chosen. This protein has a globally positive charge and a wide enough active

p38 and c-Jun N-terninal kinase (JNK) are activated in response to acute stress and inflammatory signals. Through modification of a plethora of substrates, these kinases profoundly re-shape cellular physiology for the optimal response to a harmful environment and/or an inflammatory

A low serum ceruloplasmin concentration is considered diagnostic for Wilson's disease. We aimed to evaluate an enzymatic test for ceruloplasmin oxidase activity and to compare it with the routinely used immunological ceruloplasmin measurement. Serum ceruloplasmin was measured enzymatically with o-dianisidine
