Abstract: A novel PSL family prenyltransferase has relaxed substrate specificity, which can use a variety of cyclic dipeptides and prenyl donors as substrates to produce various terpenylated diketopiperazines. An amino acid sequence of the prenyltransferase is SEQ ID NO: 1. An application of the prenyltransferase is transferring different prenyl groups to Trp-containing cyclic dipeptides. The prenyltransferase catalyzes the formation of terpenylated diketopiperazines by assembling prenyl groups onto cyclic dipeptides, which provides a new strategy for drug development of diketopiperazines.

Abstract: A frame like structure supporting a laser engraving machine between left and right vertically adjustable pedestal. Each pedestal is mounted to a set of vertically oriented screw shafts wherein at least one shaft on each side frame is driven by a stepper motor connected to the screw shaft adjacent the bottom end thereof. Manually operated locks are provided at the tops of the screw shaft to prevent inadvertent rotation caused by the weight of the engraving machine in the event of a motor failure. The pairs of screw shafts on each side of the frame are coupled by belts to permit one motor to rotate both shafts and one lock to lock both shafts.

Abstract: Exemplary embodiments relate to a protein engineering pipeline configured to optimize or improve proteins for specified functions. The problem space of such a task can grow quickly based on the sequence of the protein being optimized and the functions for which the protein is being designed. The solutions described herein allow the problem space to be efficiently searched by applying a combination of a protein design pipeline and an evaluation procedure performed on a quantum computer. As a result, single or multiple amino acid substitutions at a site of interest may be predicted in order to generate optimized protein variants.

Abstract: A method for sending a data packet includes, sending, by a transmit node, a data packet based on a target sending rate and occupation of a data sending queue, where a sending rate for sending the data packet is proportional to the target sending rate, and the occupation of the data sending queue limits a quantity of data packets. The transmit node receives a feedback message from a receive node indicating the capability of the receive node for processing the data packet. The transmit node may adjust the sending rate based on the feedback message.
