| Abstract | The plant-specific serotonin derivatives feruloylserotonin (FS) and 4-coumaroylserotonin (CS) are synthesized by the enzymes 4-coumarate:coenzyme A ligase (4CL) and serotonin N-hydroxycinnamoyltransferase (SHT). To express these genes coordinately, SHT was fused in-frame with the self-processing FDMV 2A sequence followed by 4CL in a single open reading frame and introduced into Escherichia coli or Saccharomyces cerevisiae. The transgenes were abundantly expressed in both recombinant microbes, but functional expression was achieved only in yeast, with cleavage at the 2A sequence yielding monomeric SHT-2A and 4CL as judged by immunoblot and product analyses. In the presence of an exogenous supply of precursors such as serotonin and ferulic acid, the recombinant yeast synthesized 4.5 mg l−1 FS in the medium while 0.02 mg l−1 FS was produced in the cells. Time-course analysis indicated peak accumulation of FS at 24 h after induction, and this level was maintained until 96 h. The optimum precursor concentration was 2 mM. A series of serotonin derivatives was produced by adding various cinnamate derivative precursors with serotonin; 2.5 mg l−1 caffeoylserotonin (CaS) and 1.4 mg l−1 CS were produced, whereas no sinapoylserotonin or cinnamoylserotonin was yielded. |

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.
