Abstract:
The present invention concerns a method; for genetically transforming a. Bifidobacterium strain comprising a step of methylalion of a shuttle sector in. an E. coli or a Gram-positive bacterium strain by two type II DNA methyltransferases from a Bifidobacterium :, a methyltransferase enzyme that methylates the adenine base at position 4 of the nucleotide -sequence RXCAGG and a methyltTansferase enzyme that methylates the cytosine base at position 4 of the nucleotide sequence GGWCC. The present invention also concerns genetic tools and culture media useful for carrying out said method.
Abstract:
Plants described herein have increased biomass and are more readily digested into fermentable sugars when the plants express increased levels of one or more types of CGR2 and/or CGR3 enzymes.
Abstract:
Provided herein is a non-naturally occurring microbial organism having a methanol metabolic pathway (MMP) that can enhance the availability of reducing equivalents in the presence of methanol. Such reducing equivalents can be used to increase the product yield of organic compounds produced by the microbial organism, such as 1,4-butanediol (BDO). Also provided herein are methods for using such an organism to produce BDO.
Abstract:
This disclosure relates to the isolation and sequencing of nucleic acid molecules that encode methyltransferase polypeptides from a Papaver somniferum cultivar; and uses in the production of noscapine and identification of poppy cultivars that include the genes that comprise said nucleic acid molecules.

Abstract:
PURPOSE: A method for producing L-amino acids using E.coli is provided to supplement NADPH through NADP. CONSTITUTION: An E.coli microorganism with improved L-amino acid prouctivity has enhanced NAD kinase activation and is transformed for inactivation of enzyme having an amino acid of sequence number 2. The NAD kinase activation is enhanced by copy increase, expression regulatory site substitution, modification, or genetic mutation. The L-amino acid is L-threonine or L-tryptopan. A method for producing L-amino acid comprises a step of culturing E.coli to a culture medium containing sucrose or glucose and a step of isolating L-amino acid from the culture.
