Structural characterization of the calcium binding protein s100 from adipose tissue

A partial amino acid sequence for bovine adipose tissue S100 was elucidated by characterization of peptides generated by cyanogen bromide cleavage. The cyanogen bromide peptides were aligned by homology with the bovine brain S100 beta sequence. The results demonstrate that adipose S100 beta is probably identical to brain S100 beta, and suggest that S100 beta is a conserved protein among tissues of the same species.
