| Abstract | Homma, J. Yuzuru (University of Tokyo, Tokyo, Japan), and Nachiko Suzuki. “Cell-wall protein A” of Pseudomonas aeruginosa and its relationship to “original endotoxin protein.” J. Bacteriol. 87:630–640. 1964.—To compare the properties of two kinds of proteins, one obtained from the cell wall of Pseudomonas aeruginosa and the other from the endotoxin in the autolysate, the proteins were purified to such an extent that they were proved to be homogeneous by zone electrophoretic and ultracentrifugal analyses. Although there were some differences between the two in such values as nitrogen and phosphorus contents and sedimentation constants, their protein portions were found similar to each other in the ratio of amino acid compositions. It was proved serologically that the two proteins possessed a common specific antigen. They were found to be the same in their potencies in eliciting the Shwartzman phenomenon and pyrogenic reaction. The results of pyocine tests with various sensitive strains revealed that, against the sensitive strains, the spectra of both proteins were almost the same. Their pyocine activities were destroyed through digestion by protease, trypsin, and Nagarse. Either of the rabbit antisera against the two proteins could neutralize pyocine activities of both proteins. Serum-absorption tests proved that the pyocine-neutralizing antibodies of both antisera could be completely absorbed with each of the proteins. Under appropriate conditions, their pyocine activities were masked partially in vitro by the lipopolysaccharde of the endotoxin. |

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.
