Chemical shift assignments of CHU_1110: an AHSA1-like protein from Cytophaga hutchinsonii
- 106 Downloads
AHSA1 protein family is one of the four largest families in the Bet v1-like protein superfamily. The functions and structures of proteins in AHSA1 family are still largely unknown. CHU_1110 with 167 amino acids and a molecular weight of 19.2 kDa is a member of the AHSA1 family from Cytophaga hutchinsonii, a soil bacterium known for its ability to digest crystalline cellulose. Here we report the complete 1H, 13C and 15N chemical shift assignments of CHU_1110. The secondary structural elements of CGL2373 are consistent with the canonical AHSA1 structure. However the sequence identity of CHU_1110 with other members of AHSA1 family with functional and structural reports, such as RHE_CH02687 from Rhizobium etli, Aha1 from Homo sapiens and Yndb from Bacillus subtilis, are very low, which may suggest a different function of CHU_1110. Our chemical shift assignments of CHU_1110 are essential for the following structural and functional research of CHU_1110.
