| Abstract | Gaussia luciferase (GLuc) is the smallest known bioluminescent protein and is attracting much attention as a potential reporter protein. However, its 10 disulfide bond forming cysteines have hampered the efficient production of recombinant GLuc and thus limited its use in bio-imaging application. Here, we demonstrate that the addition of a short solubility enhancement peptide tag (SEP-Tag) to the C-terminus of GLuc (GLuc-C9D) significantly increased the fraction of soluble protein at a standard expression temperature. The expression time was much shorter, and the final yield of GLuc-C9D was significantly higher than with our previous pCold expression system. Reversed phase HPLC indicated that the GLuc-C9D variant folded with a single disulfide bond pattern after proper oxidization. Further, the thermal denaturation of GLuc-C9D was completely reversible, and its secondary structure content remained unchanged until 40 °C as assessed by CD spectroscopy. The $^{1}$ H-NMR spectrum of GLuc indicated sharp well dispersed peaks typical for natively folded proteins. GLuc-C9D bioluminescence activity was strong and fully retained even after incubation at high temperatures. These results suggest that solubilization using SEP-Tags can be useful for producing large quantities of proteins containing multiple disulfide bonds. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
