The discovery of new anti-tubercular drugs is needed to face the increasing TB cases, especially to prevent the increase of cases with resistant Mtb. A potential novel drug target is the Mtb PhoR sensor domain protein which is the histidine kinase extracellular domain for receiving environmental signals. This protein is the initial part of the two-component system PhoR-PhoP regulating 114 genes related to the virulence of Mtb. In this study, the gene encoding PhoR sensor domain (SensPhoR) was subcloned from pGEM-T SensPhoR from the previous study (Suwanto, 2012) to pColdII. The construct pColdII SensPhoR was confirmed through restriction analysis and sequencing. Using the construct, SensPhoR was overexpressed at 15°C using Escherichia coli BL21 (DE3). Low temperature was chosen because according to the solubility prediction program of recombinant proteins from The University of Oklahama, the PhoR sensor domain has a chance of 79.8% to be expressed as insoluble proteins in Escherichia coli’s (E. coli) cytoplasm. This prediction is also supported by other similar programs: PROSO and PROSO II. The SDS PAGE result indicated that the PhoR sensor domain recombinant protein was overexpressed. For future studies, this protein will be purified and used for structure analysis which can be used to find potential drugs through rational drug design. © 2014 AIP Publishing LLC.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Mycobacterium tuberculosis,Over-expression,PhoR,Rational drug designs,Sensor domains[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Low temperature overexpression,Mycobacterium tuberculosis,PhoR,Rational Drug Design,Recombinant protein,Sensor domain[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4868830[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
