The T4-related bacteriophages are a group of bacterial viruses that share morphological similarities and genetic homologies with the well-studied Escherichia coli phage T4, but that diverge from T4 and each other by a number of genetically determined characteristics including the bacterial hosts they infect, the sizes of their linear double-stranded (ds)(More)
BACKGROUND Bacteriophages are an important repository of genetic diversity. As one of the major constituents of terrestrial biomass, they exert profound effects on the earth's ecology and microbial evolution by mediating horizontal gene transfer between bacteria and controlling their growth. Only limited genomic sequence data are currently available for(More)
The single-strand binding (Ssb) protein of phage T4 (T4 gp32, product of gene 32) is a mRNA-specific autogenous translational repressor, in addition to being a sequence-independent ssDNA-binding protein that participates in phage DNA replication, repair and recombination. It is not clear how this physiologically essential protein distinguishes between(More)
The Altcriss project aims to perform a long term survey of the radiation environment on board the International Space Station. Measurements are being performed with active and passive devices in different locations and orientations of the Russian segment of the station. The goal is to perform a detailed evaluation of the differences in particle fluence and(More)
Squid photoreceptor membranes contain several small GTP-binding proteins (22-27 kDa) in addition to heterotrimeric G-proteins. In addition, these membranes contain several proteins which can be ADP-ribosylated by exoenzyme C3 from Clostridium botulinum (C3). These proteins are similar but not identical to C3 substrates from bovine rod outer segments. It is(More)
Bovine brain cDNA cloned earlier and attributed to calmodulin-independent adenylate cyclase encodes the neural cell adhesion molecule (N-CAM). The expression of N-CAM mRNA in Xenopus laevis oocytes increases their basal adenylate cyclase activity. Polyclonal antibodies against synthetic peptide A, VAENQQGKSKAAHFV (664-678 amino acid residues of bovine(More)
