| Abstract | We identified the poly(hydroxyalkanoate) synthase (PHAS) genes of three strains of Pseudomonas oleovorans by using polymerase chain reaction (PCR)-based detection methods. P. oleovorans NRRL B-14682 contains Class I PHA synthase gene (phaC), NRRL B-14683 harbors Class II phaC1 and phaC2 genes, and NRRL B-778 contain both the Class I and II PHA synthase genes. Inverse-PCR and chromosomal walking techniques were employed to obtain the complete sequences of the Class I phaCs of NRRL B-778 (phbC778; 1698 bps) and B-14682 (phbC14682; 1899 bps). BLAST search indicated that these genes are new and had not been previously cloned. The gene product of phbC778 (i.e., PhbC778; 566 amino acid residues) is homologous to the Class I PHA synthases of Pseudomonas sp. HJ-2 and Pseudomonas sp. strain 61-3, and that of phbC14682 (PhbC14682; 632 amino acids) is homologous to PHAS of Delftia acidovorans. The PhbC14682 contains an extra sequence of 33 amino acids in its conserved α/β-hydrolase domain, making it only the second Class I PHA synthase found to contain this cellular proteolytic sequence. Consistent with their Pseudomonas origin, the codon-usage profiles of PhbC778 and PhbC14682 are similar to those of Pseudomonas Class II PHASs. These new Pseudomonas Class I phbC genes provide valuable addition to the gene pool for the construction of novel PHASs through gene shuffling. |

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.
