traumatic brain injury (tbi) is physical damage to the brain structure which has a high global rate of mortality and morbidity. tbi can cause intense inflammatory response due to accumulation of leukocytes in cerebral matrix and activation of microglia. microglia can differentiate into m1 macrophages or m2 macrophages following the changes in biochemical properties of brain tissue. m1 sub type ...

Proteins of the animal heme peroxidase (ANP) superfamily differ greatly in size since they have either one or two catalytic domains that match profile PS50292. The orf PP_2561 of Pseudomonas putida KT2440 that we have called PepA encodes a two-domain ANP. The alignment of these domains with those of PepA homologues revealed a variable number of insertions with the consensus G-x-D-G-x-x-[GN]-[TN...

The yeast DEAD-box protein Has1p is required for the maturation of 18S rRNA, the biogenesis of 40S r-subunits and for the processing of 27S pre-rRNAs during 60S r-subunit biogenesis. We purified recombinant Has1p and characterized its biochemical activities. We show that Has1p is an RNA-dependent ATPase in vitro and that it is able to unwind RNA/DNA duplexes in an ATP-dependent manner. We also ...

Oligoamide strands containing tertiary amide groups were found to share a basic structural motif that promotes the formation of H-bonded, chain- or tape-like supramolecular assemblies.
