Abstact

The crystal structure of ST1625p, a protein encoded by a hypothetical open reading frame ST1625 in the genome of the hyperthermophilic archaeon Sulfolobus tokodaii, was determined at 2.2 A resolution. The only sequence similarity exhibited by the amino-acid sequence of ST1625p was a 33% identity with the sequence of SSO0983p from S. solfataricus. The 19 kDa monomeric protein was observed to consist of a right-handed superhelix assembled from a tandem repeat of ten alpha-helices. A structural homology search using the DALI and MATRAS algorithms indicates that this protein can be classified as a helical repeat protein.
