Molecular Relatedness

The determination of the nucleotide sequences of the 11 streptococcal SAgs listed above allowed the establishment of their amino acid sequences which revealed various degrees of molecular and structural relatedness at both amino acid sequences and three-dimensional (3-D) levels. These SAgs were found to share important structural homologies or similarities with S. aureus enterotoxin SAgs. Interestingly, certain streptococcal SAgs are more similar to some staphylococcal SAgs than to other streptococcal SAgs.[14] The genomic and structural relatedness suggests that these SAgs share a common ancestor.[17,18]

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
