| Abstract | Nitric oxide-stimulated modification of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) by [adenylate-32P]NAD has been interpreted in recent reports as ADP-ribosylation. Incubations of GAPDH with the NO-releasing agent sodium nitroprusside (SNP) and NAD resulted, however, in essentially equal incorporation of radiolabel from the adenine, phosphate, and nicotinamide moieties to the extent of approximately 0.02 mol of NAD.mol of GAPDH-1. Modification of GAPDH by free adenosine 5'-diphosphoribose (ADP-ribose) was only 10% of that by NAD. Exposure of GAPDH modified by NAD in the presence of SNP to HgCl2, which acts at thiol linkages, released two products. Both contained nicotinamide and adenylate but did not cochromatograph with NAD. GAPDH activity was inhibited by SNP in a dose-dependent manner in the presence of NAD. When inhibition was 80%, with 1 mM SNP and 1 mM dithiothreitol, covalent modification with NAD was < 2%. This result is consistent with the conclusion that inhibition of GAPDH activity by SNP in the presence of NAD is due primarily to active-site nitrosylation, as reported by other workers, and is not due to the minor modification with NAD. These results demonstrate that NO-stimulated modification of GAPDH with NAD is not ADP-ribosylation as previously reported but rather is covalent binding of NAD through a NO-dependent thiol intermediate, possibly providing an example of an unexpected, altered reactivity of a nitrosylated protein. |

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.
