New investigation results, "Spontaneous formation of L-isoaspartate and gain of function in fibronectin," are detailed in a study published in Journal of Biological Chemistry. "Isoaspartate formation in extracellular matrix proteins, by aspartate isomerization or asparagine deamidation, is generally viewed as a degradation reaction occurring in vivo during tissue aging. For instance, non-enzymatic isoaspartate formation at RGD-integrin binding sites causes loss of cell adhesion sites, which in turn can be enzymatically "repaired" to RGD by protein-l-isoAsp-O-methyltransferase," investigators in Milan, Italy report.

"We show here that isoaspartate formation is also a...
