Protein Classification

peroxiredoxin-like family protein( domain architecture ID 10121943)

peroxiredoxin (PRX)-like family protein containing a CXXC motif, with the second cysteine in the motif corresponding to the peroxidatic cysteine of PRX, however, it does not contain the other two residues of the catalytic triad of PRXs; similar to vertebrate peroxiredoxin-like 2A, 2B (prostamide/prostaglandin F synthase) and 2C

Peroxiredoxin (PRX)-like 2 family; hypothetical proteins that show sequence similarity to PRXs. ...
 31-193 5.13e-46

Peroxiredoxin (PRX)-like 2 family; hypothetical proteins that show sequence similarity to PRXs. Members of this group contain a CXXC motif, similar to TRX. The second cysteine in the motif corresponds to the peroxidatic cysteine of PRX, however, these proteins do not contain the other two residues of the catalytic triad of PRX. PRXs confer a protective antioxidant role in cells through their peroxidase activity in which hydrogen peroxide, peroxynitrate, and organic hydroperoxides are reduced and detoxified using reducing equivalents derived from either thioredoxin, glutathione, trypanothione and AhpF. TRXs alter the redox state of target proteins by catalyzing the reduction of their disulfide bonds via the CXXC motif using reducing equivalents derived from either NADPH or ferredoxins.

 36-206 4.90e-10

SelL-related redox protein; Members of this family are related to the C-terminal region of selenoprotein L (SelL), found in many non-mammalian animals. But while SelL itself has a pair of selenocysteine (U) residues (e.g. XP_029705782.1), typically in the motif ULPU, this family is defined more broadly. Most members of the seed alignment for this HMM are bacterial proteins that have one or zero selenocysteine residues, and are shorter than SelU, although SelU members are also included.
