Polymerase and Histidinol Phosphatase domain; The PHP (also called histidinol phosphatase-2/HIS2) domain is associated with several types of DNA polymerases, such as PolIIIA and family X DNA polymerases, stand alone histidinol phosphate phosphatases (HisPPases), and a number of uncharacterized protein families. The PHP domain has four conserved sequence motifs and contains an invariant histidine that is involved in metal ion coordination. PHP in polymerases has trinuclear zinc/magnesium dependent proofreading activity. It has also been shown that the PHP domain functions in DNA repair. The PHP structures have a distorted (beta/alpha)7 barrel fold with a trinuclear metal site on the C-terminal side of the barrel.

Polymerase and Histidinol Phosphatase domain of Histidinol phosphate phosphatase of Hisj like; Bacillus subtilis YtvP HisJ has strong histidinol phosphate phosphatase (HisPPase) activity. The PHP (also called histidinol phosphatase-2/HIS2) domain is associated with several types of DNA polymerases, such as PolIIIA and family X DNA polymerases, stand alone histidinol phosphate phosphatases (HisPPases), and a number of uncharacterized protein families. HisPPase catalyzes the eighth step of histidine biosynthesis, in which L-histidinol phosphate undergoes dephosphorylation to produce histidinol. The PHP domain has four conserved sequence motifs and contains an invariant histidine that is involved in metal ion coordination. The PHP domain of HisPPase is structurally homologous to other members of the PHP family that have a distorted (beta/alpha)7 barrel fold with a trinuclear metal site on the C-terminal side of the barrel.

histidinol phosphate phosphatase, HisJ family; This model represents the histidinol phosphate phosphatase HisJ of Bacillus subtilis, and related proteins from a number of species within a larger family of phosphatases in the PHP hydrolase family. HisJ catalyzes the penultimate step of histidine biosynthesis but shows no homology to the functionally equivalent sequence in E. coli, a domain of the bifunctional HisB protein. Note, however, that many species have two members and that Clostridium perfringens, predicted not to make histidine, has five members of this family; this family is designated subfamily rather than equivalog to indicate that members may not all act as HisJ.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
