    Protein Summary

    TM1464 encodes an indigoidine synthase A (IdgA)-like protein from Thermotoga maritima (pfam04227; COG2313). Indigoidine is a blue pigment first described in Erwinia chrysanthemi implicated in pathogenicity and protection from oxidative stress [Ref]. IdgA is involved in indigoidine biosynthesis, but its specific function is unknown. Analysis of TM1464 genome context indicates a functional link (score 0.825) with TM1465, a cob(I)alamin adenosyltransferase.

    TM1464 structure, 1vkm, represents a novel fold (Indigoidine synthase A-like; SCOP sunid:110580), with a 3 layers (alpha/beta/alpha) core containing a parallel beta-sheet of 7 strands (order: 2134756). A DALI search returns no significant hits.

    Analysis of the crystallographic packing of 1vkm using the PQS server {Henrick, 1998 #73} indicates that an hexamer is the biologically relevant form.
