Ubiquitin-conjugating enzyme, active site (IPR023313) Ubiquitin-conjugating enzymes (, UBC or E2 enzymes) catalyze the covalent attachment of ubiquitin to target proteins. An activated ubiquitin moiety is transferred from an ubiquiti...

Histidine acid phosphatase active site (IPR033379) Histidine acid phosphatases are a heterogeneous group of proteins that hydrolyse phosphate esters, optimally at low pH. It has been shown that a number of acid phosphatases, from ...

Urease active site (IPR017950) Urease (urea amidohydrolase) is a nickel-binding enzyme that catalyses the hydrolysis of urea to carbon dioxide and ammonia. Historically, it was the first enzyme to be crystalliz...

Asparaginase/glutaminase, active site 1 (IPR020827) Asparaginase, which is found in various plant, animal and bacterial cells, catalyses the deamination of asparagine to yield aspartic acid and an ammonium ion, resulting in a deple...

Phenylalanine/histidine ammonia-lyases, active site (IPR022313) This entry represents the active site of phenylalanine ammonia-lyase (PAL;) and the mechanistically related protein histidine ammonia lyase (HAL;). Both contain a catalytic Ala-Se...

Phosphoenolpyruvate carboxylase, Lys active site (IPR018129) Phosphoenolpyruvate carboxylase (PEPcase) catalyzes the irreversible beta-carboxylation of phosphoenolpyruvate by bicarbonate to yield oxaloacetate and phosphate. The enzyme is fo...

Ribonucleotide reductase small subunit, acitve site (IPR030475) Ribonucleotide reductase catalyses the reductive synthesis of deoxyribonucleotides from their corresponding ribonucleotides. It provides the precursors necessary for DNA synthesis...

Asp/Glu racemase, active site 1 (IPR018187) Aspartate racemase and glutamate racemase are two evolutionary related bacterial enzymes that do not seem to require a cofactor for their activity. Glutamate racemase, which inter...

Ribonuclease T2, His active site 1 (IPR018188) The fungal ribonucleases T2 from Aspergillus oryzae, M from Aspergillus saitoi and Rh from Rhizopeus niveus are structurally and functionally related 30 Kd glycoproteins that clea...

Phospholipase A2, aspartic acid active site (IPR033112) Phospholipase A2 (PLA2) is a small lipolytic enzyme that releases fatty acids from the second carbon group of glycerol. It is involved in a number of physiologically important cel...
