| Abstract | The determination of the secondary structure topology is a critical step in deriving the atomic structure from the protein density map obtained from electron cryo-microscopy technique. This step often relies on the matching of two sources of information. One source comes from the secondary structures detected from the protein density map at the medium resolution, such as 5-10 Å. The other source comes from the predicted secondary structures from the amino acid sequence. Due to the uncertainty in either source of information, a pool of possible secondary structure positions has to be sampled in order to include the true answer. A naïve way to find the native topology is to exhaustively map the pool of possible secondary structures detected in the density map with the pool of the secondary structures predicted from the sequence and search for the topology with the lowest cost. This paper studies the question that is how to reduce the computation of the mapping when the uncertainty of the secondary structure predictions is considered. We present a method that combines the concept of dynamic graph with our previous work of using constrained shortest path to identify the topology of the secondary structures. We show a reduction of about 34.55% time as comparison to the naïve way of handling the inaccuracies. To our knowledge, this is the 1st computationally effective exact algorithm to identify the optimal topology of the secondary structures when the inaccuracy of the predicted data is considered. |

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.
