    Protein Summary

    The CC_2267 gene from Caulobacter crescentus CB15 encodes the NP_421070 amino acid sequence that belongs to the Dabb group (PF07876, cl06768). Currently, its function is unknown but a homolog in a plant, Populus balsamifera, is upregulated when exposed to higher concentrations of salt.

    Its structure, 3bn7, belongs to the alpha+beta class, ferredoxin-like fold, dimeric alpha+beta barrel superfamily, plant stress induce protein family (cf. SCOP, CATH). Proteins belonging to this family adopt an alpha/beta barrel (also known as a 2 layer sandwich) with an internal duplication. 3bn7 protein fold is also found in other PSI determined bacterial protein structures like 3bde (Dali Zscr=13; with sequence identity of 26%), 3bgu (Z=12), 2qyc (Z=12), 3bb5 (Zscr=12), and 3fmb (Zscr=12; sequence identity 22%). DALI top hit is with 1tr0 (Z=15).

    The likely biologically functional unit of 3bn7 is a dimer.
