文摘

Nucleotide sequences of the C. roseus SRA database were assembled and translated in order to detect putative universal stress proteins (USPs). Based on the known conserved USPA domain, 24 Pfam putative USPA proteins in C. roseus were detected and arranged in six architectures. The USPA-like domain was detected in all architectures, while the protein kinase-like (or PK-like), ^tyrPK-like and/or U-box domains are shown downstream it. Three other domains were also shown to coexist with the USPA domain in C. roseus putative USPA sequences. These domains are tetratricopeptide repeat (or TPR), apolipophorin III (or apoLp-III) and Hsp90 co-chaperone Cdc37. Subsequent analysis divided USPA-like domains based on the ability to bind ATP. The multiple sequence alignment indicated the occurrence of eight C. roseus residues of known features of the bacterial 1MJH secondary structure. The data of the phylogenetic tree indicated several distinct groups of USPA-like domains confirming the presence of high level of sequence conservation between the plant and bacterial USPA-like sequences.
