| Abstract | Sequencing techniques for single- and double-stranded DNA were used to determine the nucleotide sequence of the gene encoding P2, the major outer membrane (porin) protein of Haemophilus influenzae type b (Hib). The open reading frame encoding the P2 protein comprised 361 amino acid codons. Comparison of the inferred amino acid sequence with data obtained by amino acid sequencing of the N terminus of the mature or fully processed P2 protein revealed that this protein has a signal peptide composed of 20 amino acids. N-terminal amino acid sequencing of tryptic peptides derived from purified P2 allowed direct identification of 158 of the 341 amino acids in the fully processed P2 protein; there was 100% correlation between these amino acid sequences and that inferred from the nucleotide sequence. The amino acid sequence of Hib P2 protein had 23 to 25% homology with the sequence of the OmpF porin of Escherichia coli and with that of the Neisseria gonorrhoeae porin P.IA. Codon usage in the Hib P2 gene was significantly different from that observed for a gene encoding a porin of E. coli. DNA hybridization studies indicated that there is a single copy of the P2 gene in the Hib chromosome. The availability of the nucleotide and amino acid sequences for the Hib P2 protein will facilitate investigation of the antigenic characteristics and structure-function relationship of this porin. |

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.
