Abstract: Methods and kits are disclosed for measuring activity of a methyltransferase or a radical SAM enzyme or for screening for an inhibitor of a methyltransferase or a radical SAM enzyme, where the methods and kits comprise, respectively, deaminase TM0936 for a MTase coupled assay and deaminase PA3170 for a radical SAM coupled assay.

Abstract: Disclosed are methods for chemoenzymatic synthesis of S-Nucleosyl Amino acid probes (SNA), analogs of S-adeno-syl-L-methionine and S-adenosyl-L-homo-cysteine, analogs synthesized by the methods, and uses thereof.

Abstract: There is provided a method for monitoring and control of heating food portions in heaters, each installed in communication with a respective client computer in communication with a same server, the method performed by the server comprising: receiving from the client computers, RF signatures, each RF signature being based on measured reflections of RF signals transmitted within a cavity of one of the heaters containing therein a food portion, analyzing the RF signatures, determining for each heater based on the analysis of the RF signatures, at least one heating instruction to operate each heater to heat the food portion therein; and transmitting to each of the client computers, the respective at least one determined heating instruction comprising instructions to generate RF signals and transmit the RF signals to the food portions using heating antennas of the heater.

Abstract: A method is provided for use in calibrating a plurality of antennas comprised in an antenna array and wherein the antenna array comprises at least one gain control circuitry.

Abstract: A multi-transmitter base station for wireless digital communication, having beam forming and digital pre-distortion capabilities, including a shared feedback unit for providing feedback of outgoing Radio Frequency (RF) signals for calibrating a plurality of antennas and for adapting the digital pre-distortion. Related apparatus and methods are also described.
