Glc7p is an essential serine/threonine type 1 protein phosphatase (PP1) from the yeast Saccharomyces cerevisiae, which has a role in many processes including cell cycle progression, sporulation, glycogen accumulation, translation initiation, and glucose repression. Two hallmarks of PP1 enzymes are very high amino acid sequence conservation and association(More)
Multimedia authentication techniques are required to prove the validity of legal multimedia content and establish the identity of the content creator. Digital signatures are one way of authenticating multimedia content. Typically digital signatures use cryptographic techniques to ensure the integrity of the multimedia bitstream. This paper proposes a hard(More)
Inhibitor-1 (I-1), a cyclic AMP-regulated phosphoprotein, inhibits protein phosphatase-1 (PP1) activity in response to hormones. The molecular mechanism for PP1 inhibition by I-1 remains unknown. Mutation of nine acidic residues lining a proposed I-1-binding channel in rabbit PP1alpha yielded one mutant (E256A) slightly impaired in its inhibition by I-1,(More)
Transmission of multimedia content over a high-speed network such as ATM for applications such as Video on Demand (Vod) is slated to become one of the fastest emerging applications in the real world. Due to the low delay and high QoS (Quality of service) constraint posed by these applications, various issues arise such as selection of AAL (ATM Adaptation(More)
With the innovations and development in sophisticated video editing technology and a wide spread of video information and services in our society, it is becoming increasingly significant to assure the trustworthiness of video information. Therefore in surveillance, medical and various other fields, video contents must be protected against attempt to(More)
Riboflavin binding protein (RfBP) is one of the several nutrient-binding proteins with primary function of depositing riboflavin in the egg. Riboflavin binding protein was isolated and purified from Ostrich (Struthio camelus) egg white and yolk by DEAE Sepharose ion exchange chromatography followed by gel filtration chromatography on Sephadex G-100. The(More)
