== Publication Abstract from PubMed ==

Galacto-N-biose/lacto-N-biose I phosphorylase (GLNBP) is the key enzyme in the enzymatic production of lacto-N-biose I. For the purpose of industrial use, we improved the thermostability of GLNBP by evolutionary engineering in which five substitutions in the amino acid sequence were selected from a random mutagenesis GLNBP library constructed using error-prone polymerase chain reaction. Among them, C236Y and D576V mutants showed considerably improved thermostability. Structural analysis of C236Y revealed that the hydroxyl group of Tyr236 forms a hydrogen bond with the carboxyl group of E319. The C236Y and D576V mutations together contributed to the thermostability. The C236Y/D576V mutant exhibited 20 degrees C higher thermostability than the wild type.
