Abstract excerpt
The glycoside hydrolase family 1 members Os4BGlu14, Os4BGlu16, and Os4BGlu18 were proposed to be rice monolignol β-glucosidases. In vitro studies demonstrated that the Os4BGlu16 and Os4BGlu18 hydrolyze the monolignol glucosides coniferin and syringin with high efficiency compared to other substrates. The replacement of the conserved catalytic acid/base glutamate residue by a nonionizable glutamine residue in...
