GenProp0481 urea carboxylase/allophanate hydrolase pathway~This two-step, ATP-dependent pathway for urea hydrolysis is an alternative to urease. Urease requires a transporter and accessory proteins to produce its nickel metallocenter, while this two-step system uses biotin. Urea carboxylase acts first in this pathway, requiring ATP and bicarbonate as substrates. Allophanate hydrolase acts next, but note that this enzyme may be found in systems that do not contain a urea carboxylase. In yeasts such as Saccaromyces cerevisiae, the two activities of this pathway are encoded in a fusion protein, designated urea amidolyase. This pathway appears to function primarily for the purpose of obtaining nitrogen in the form of ammonia. A pair of uncharacterized, tandem, homologous genes, restricted to organisms with this system and adjacent to the known genes, has been added to this Genome Property.

GenProp0743 urea ABC transporter UrtABCDE~This property represents a conserved five-gene operon for an ABC transporter with a substrate-binding protein, two permeases, and two ATP-binding cassette proteins. All five genes from this operon are detected in Burkholderia mallei, at very high confidence levels, by means of the partial phylogenetic profiling algorithm (PMID:16930487) vs. a profile for urease, and the operon occurs next to urease genes in B. mallei and most other species. In Cyanobacteria, high-affinity urea transport is shown to be eliminated by mutations to any of several different proteins in this system (PMID:11929526).

GenProp0051 urease~Urease is a multi-subunit, nickel-containing enzyme required for the hydrolysis of urea to carbon dioxide and ammonia [1]. Its three structural genes are located in an unidirectionally transcribed gene cluster consisting either as separate alpha, beta, and gamma subunits, or as in Helicobacter pylori, a fusion of beta and gamma subunits [2]. Associated with these structural subunits are accessory factors functioning to assemble and incorporate its nickel-containing metallocenter [3]. This property predicts a urease system to be present if both its three structural subunits and four accessory proteins are all found. In Bacillus subtilis, the accessory proteins are not found by homology but urease function has been shown experimentally. This finding raises the question of what alternative mechanism can enable the assembly of functional urease. Both - {{t,f}} True - {{t}} Ambiguous presence
