The catalytic domain of hexameric long form HisGL2; contains the type 2 periplasmic binding protein fold; Encoded by the hisG gene, the ATP phosphoribosyltransferase (ATP-PRT, EC 2.4.2.17) is the first enzyme in histidine biosynthetic pathway that catalyzes the condensation of ATP and PRPP (5'-phosphoribosyl 1'-pyrophosphate), and is regulated by a feedback inhibition from the product histidine. ATP-PRT has two distinct forms: a hexameric long form, HisGL, containing two catalytic domains and a C-terminal regulatory domain; and a hetero-octomeric short form, HisGs, without the regulatory domain. HisGL is catalytically competent, but the hetero-octameric HisGs requires the second subunit HisZ, a paralog to the catalytic domain of functional histidyl-tRNA synthetases (HisRSs), for the enzyme activity. This catalytic domain belongs to the type 2 periplasmic binding fold protein superfamily (PBP2). The PBP2 proteins are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. The majority of PBP2 proteins function in the uptake of small soluble substrates in eubacteria and archaea.

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.

(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
