This disclosure relates to modified tryptophan synthase and more particularly to modified beta-subunits of tryptophan synthase. The disclosure further relates to cells expressing such modified subunits and methods of producing non-canonical amino acids.
摘要:
A water purification anode has a first semiconductor contacting a second semiconductor at a heterojunction. The second semiconductor includes TiO2 and excludes bismuth and niobium. The first semiconductor includes iridium. In some instances, the anode includes a current collector in direct physical contact with the first semiconductor. The anode can be arranged in water such that at least one face of the second semiconductor is in direct physical contact with the water.
摘要:
The solar fuels generator includes an ionically conductive separator between a gaseous first phase and a second phase. A photoanode uses one or more components of the first phase to generate cations during operation of the solar fuels generator. A cation conduit is positioned provides a pathway along which the cations travel from the photoanode to the separator. The separator conducts the cations. A second solid cation conduit conducts the cations from the separator to a photocathode.

摘要:
Nucleic acids encoding cytochrome P450 variants are provided. The cytochrome P450 variants of have a higher alkane-oxidation capability, alkene-oxidation capability, and/or a higher organic-solvent resistance than the corresponding wild-type or parent cytochrome P450 enzyme. A preferred wild-type cytochrome P450 is cytochrome P450 BM-3. Preferred cytochrome P450 variants include those having an improved capability to hydroxylate alkanes and epoxidate alkenes comprising less than 8 carbons, and have amino acid substitutions corresponding to V78A, H236Q, and E252G of cytochrome P450 BM-3. Preferred cytochrome P450 variants also include those having an improved hydroxylation activity in solutions comprising co-solvents such as DMSO and THF, and have amino acid substitutions corresponding to T235A, R471A, E494K, and S1024E of cytochrome P450 BM-3.
