Biological Change / On-the-fly Untemplated Protein Modifications

JB

A HUGE new discovery - it appears that cells can react to cell stresses, and then start building modified proteins to account for the stress.  These modifications are not genetically coded. 

In the specific test case, cells reacted to the presence of reactive oxygen species (ROS) by adding methionines into proteins at various locations to protect the protein's function.  The sulfur in methionine helps protect against ROS in the cell.

Here is the writeup in science daily.

HT to Darwin's God.
