Abstract: The present disclosure provides MTR kinase polypeptides having improved properties as compared to a naturally occurring wild-type MTR kinase polypeptide including the capability of phosphorylating D-ribose and 5?-D-isobutyrylribose to give alpha-D-ribose-1-phosphate and alpha 5?-D-isobutyrylribose-1-phosphate. Also provided are polynucleotides encoding the MTR kinase polypeptides, host cells capable of expressing the MTR kinase polypeptides, and methods of using the MTR kinase polypeptides to synthesize alpha-D-ribose-1-phosphate and alpha 5?-D-isobutyrylribose-1-phosphate.

Abstract: In one embodiment, a client computing device stores a plurality of digital media files. For each digital media files, the client computing device stores data identifying a geographic location associated with the digital media file. When the client computing device receives a request to view digital media files through a graphical user interface, the client computing device uses a GPS receiver to determine a geographic location of the client computing device and an electronic compass circuit to determine an orientation of the client computing device. Based, at least in part, on the location and orientation of the client computing device, the client computing device identifies a plurality of particular geographic locations that are associated with one or more digital media files. The client computing device displays icons corresponding to the plurality of particular geographic locations, ordered by a distance from the client computing device to each of the location.

Abstract: Systems, methods, and computer-readable storage media for enabling participant following in an electronic conference. An example method can involve generating a graphical interface for an electronic conference including a group of participants, the graphical interface displaying an active participant in a first display region and a panel of respective graphical participant representations in a second display region. The method can further involve receiving, via the graphical interface, an input requesting to move at least one of the respective graphical participant representations out of the panel in the second display region to a location in the first display region of the graphical interface, and based on the input, updating the graphical interface to display the at least one of the respective graphical participant representations in the first display region.
