Abstract:
The present invention relates to a method of separating and analyzing a mixture of oligonucleotides, including performing liquid chromatography using a column packed with a packing material obtained by fixing a diol to a surface of each of porous particles formed of a crosslinked organic polymer. According to this method, the oligonucleotides can be separated and analyzed with higher sensitivity compared to cases where columns having silica gel as a base material are used. In addition, the column can be washed with an alkaline solution.
Abstract:
A method of manufacturing 1,4-butanediol, using a microbe and/or a culture thereof, by an enzyme reaction system that uses acetoacetyl-CoA reductase and enoyl-CoA hydratase, via acetoacetyl-CoA, 3-hydroxybutyryl-CoA and crotonyl-CoA in this order, wherein each of the acetoacetyl-CoA reductase and the enoyl-CoA hydratase is specific to a stereoisomer of 3-hydroxybutyryl-CoA.
Abstract:
A method of manufacturing a butanediol includes a step of culturing a microbe that contains a gene that codes acetoacetyl-CoA synthase that catalyzes a reaction that irreversibly produces acetoacetyl-CoA from acetyl-CoA and malonyl-CoA, acetoacetyl-CoA reductase that catalyzes a reaction that produces 3-hydroxybutyryl-CoA from acetoacetyl-CoA, and an enzyme that catalyzes a reaction for producing a butanediol from 3-hydroxybutyryl-CoA.
Abstract:
A method of manufacturing 1,4-butanediol through acetyl-CoA, acetoacetyl-CoA, 3-hydroxybutyryl-CoA, crotonyl-CoA, and 4-hydroxybutyryl-CoA by using a microbe and/or a culture thereof, wherein the microbe in the manufacturing method for 1,4-butanediol includes any one of genes among (a) a gene that has a base sequence of sequence number 1, (b) a gene that has a base sequence such that one or more bases are deleted, substituted, or added in a base sequence of sequence number 1, wherein the gene has a base sequence with an identity greater than or equal to 90% with respect to the base sequence of sequence number 1, and (c) a gene that hybridizes with a gene that has a base sequence complementary with a gene that has a base sequence described in sequence number 1 on a stringent condition, and includes any one or more genes among (d) genes that have base sequences of sequence numbers 2 to 9, (e) genes that have base sequences such that one or more bases are deleted, substituted, or added in base sequences of sequence numbers 2 to 9, wherein the genes have base sequences with an identity greater than or equal to 90% with respect to original base sequences thereof, and (f) genes that hybridize with genes that have base sequences complementary with genes that have base sequences of sequence numbers 2 to 9 on a stringent condition.
Abstract:
A method of manufacturing 1,4-butanediol by an enzyme reaction system via 3-hydroxybutyryl-CoA, crotonyl-CoA and 4-hydroxybutyryl CoA, in this order, using a microbe and/or a culture thereof, wherein the 3-hydroxybutyryl-CoA is an optically active substance, and wherein the microbe includes (1) a gene that codes enoyl-CoA hydratase, (2) a gene that codes vinylacetyl-CoA delta-isomerase, (3) a gene that codes 4-hydroxybutyryl CoA dehydratase, and (4) a gene that codes acyl-CoA reductase whose substrate specificity has an optical selectivity opposite to that of the 3-hydroxybutyryl-CoA.
Abstract:
A gene is selected from the group consisting of a gene (a) that has a base sequence of sequence number 1, a gene (b) that has a base sequence such that one or more bases are deleted, substituted, or added in a base sequence of sequence number 1, wherein the gene (b) has a base sequence with an identity greater than or equal to 90% with respect to the base sequence of sequence number 1, and a gene (c) that hybridizes with a gene that has a base sequence complimentary with a gene that has a base sequence of sequence number 1 on a stringent condition, wherein the selected gene in combination with a gene that codes enoyl-CoA hydratase is able to provide a microbe or a culture of the microbe with an ability to convert 3-hydroxybutyryl-CoA into 4-hydroxybutyryl-CoA or 4-hydroxybutyryl-CoA into 3-hydroxybutyryl-CoA.
