In addition to them, 22 stemmed organisms of unknown nature were recorded.
Three "additional" positions (86, 88 and 101) were also usually pulled up to the state optimal for the given temperature conditions. All this happened many times independently in different evolutionary lines.The authors even managed to figure out in general terms why the replacement of aspartic acid with serine in position 103 reduces the activity, but increases the stability of the enzyme. For high activity, the amino acid residue needs to form a strong hydrogen bond with the substrate. Continue reading “In addition to them, 22 stemmed organisms of unknown nature were recorded.”
