carbamoyl-phosphate synthase, large subunit; Carbamoyl-phosphate synthase (CPSase) catalyzes the first committed step in pyrimidine, arginine, and urea biosynthesis. In general, it is a glutamine-dependent enzyme, EC 6.3.5.5, termed CPSase II in eukaryotes. An exception is the mammalian mitochondrial urea-cycle form, CPSase I, in which the glutamine amidotransferase domain active site Cys on the small subunit has been lost, and the enzyme is ammonia-dependent. In both CPSase I and the closely related, glutamine-dependent CPSase III (allosterically activated by acetyl-glutamate) demonstrated in some other vertebrates, the small and large chain regions are fused in a single polypeptide chain. This model represents the large chain of glutamine-hydrolysing carbamoyl-phosphate synthases, or the corresponding regions of larger, multifunctional proteins, as found in all domains of life, and CPSase I forms are considered exceptions within the family. In several thermophilic species (Methanobacterium thermoautotrophicum, Methanococcus jannaschii, Aquifex aeolicus), the large subunit appears split, at different points, into two separate genes.

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.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(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)
the domain superfamily to which the specific and non-specific hits belong
