    摘要： The present invention relates to a driving device. The driving device according to the present invention includes a main transistor that supplies a current to a load by using a power supply, an auxiliary transistor that drops a predetermined voltage of the voltage of the power supply and transmits the dropped voltage to the main transistor in a turn-on state, and a bypass switch that transmits the voltage of the power supply to the main transistor when the auxiliary transistor is turned off.

    摘要： Disclosed is an O-phosphoserine sulfhydrylase (OPSS) mutant which has a Mycobacterium smegmatis-derived amino acid sequence corresponding to that of SEQ ID NO: 1 which is devoid of three to seven C-terminal amino acid residues. Also, a nucleic acid molecule encoding the OPSS mutant, an expression vector carrying the nucleic acid molecule, and a transformant transformed with the expression vector are disclosed. In addition, a method is provided for producing cysteine in which O-phospho-L-serine (OPS) is reacted with a sulfide in the presence of the OPSS mutant. The OPSS mutant has improved enzymatic activity and can be applied to the environmentally friendly production of L-cysteine through a simple enzymatic conversion reaction.
