== Publication Abstract from PubMed ==
 +
The structure of the trimeric adenylate kinase from the Archaebacteria Methanococcus mariplaludis (AK(MAR)) has been solved to 2.5-A resolution and the temperature dependent stability and kinetics of the enzyme measured. The K(M) and V(max) of AK(MAR) exhibit only modest temperature dependence from 30 degrees -60 degrees C. Although M. mariplaludis is a mesophile with a maximum growth temperature of 43 degrees C, AK(MAR) has a very broad functional range and stability (T(m) = 74.0 degrees C) that are more consistent with a thermophilic enzyme with high thermostability and exceptional activity over a wide range of temperatures, suggesting that this microbe may have only recently invaded a mesophilic niche and has yet to fully adapt. A comparison of the Local Structural Entropy (LSE) for AK(MAR) to the related adenylate kinases from the mesophile Methanococcus voltae and thermophile Methanococcus thermolithotrophicus show that changes in LSE are able to fully account for the intermediate stability of AK(MAR) and highlights a general mechanism for protein adaptation in this class of enzymes.
