The lipase from Burkholderia glumae (BGL) was incubated at variable temperature, pH and concentration of organic solvents, and the decrease of enzymatic activity was compared to changes in the molecular structure as monitored by ESI-mass spectrometry. We observed that deactivation is not strictly related to structural instability in the assay conditions, in fact (i) thermal deactivation preceded denaturation;...
New fluorobenzene chromium dicarbonylisocyanide complexes have been synthesized and evaluated in terms of their 'in solution' reactivity towards some nucleophiles. For the first time the polymer-bound isocyanides have been found to be valuable ligands for anchoring haloareneCr(CO) 3 complexes by means of their substitution for a CO group. The supported fluorobenzene complex reacted with nitrogen-nucleophiles.
