The present disclosure provides engineered transaminase enzymes having improved properties as compared to a naturally occurring wild-type transaminase enzyme. Also provided are polynucleotides encoding the engineered transaminase enzymes, host cells capable of expressing the engineered transaminase enzymes, and methods of using the engineered transaminase enzymes to synthesize a variety of chiral compounds.

Transaminase polypeptides

Disclosed are methods and apparatus for providing portable or fixed solar array support systems. Embodiments of the invention include an apparatus that holds two multi-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments.

Compact portable foldable solar panel support system and methods of use

Disclosed are methods and apparatus for providing portable or fixed solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments.

Disclosed are hinges having specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. In some embodiments, the stops may limit the hinges to open no more than 90 degrees. In other embodiments the stops may limit the hinges to open no more than 180 degrees. The hinges provide stability to any structure they are used with.

Disclosed are methods and apparatus for providing portable solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments. Embodiments of the foldable solar array system are constructed from steel components, and feature proprietary integrated hinges to minimize the size and complexity of the system. The hinges are specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. These may be 90&#xb0; hinges on the panel arms and swing arms, and may be 180&#xb0; hinges on panel-to-panel hinges. The panel-to-panel hinges also allow for an offset based on the thickness of the solar panels and make the solar panels lay flat when open and stack face to face when closed. The weight from the use of steel is useful to help stabilize the array in windy conditions. Additional weight and/or ground anchors can also be easily applied and are recommended for use in windy environments.
