Haloacid dehalogenase-like hydrolase domain containing 2 (2HO4:A,B)

Where's does this name come from?

Hydolase indicates it's main molecular function, hydrolase activity. /Link


Definition of hydrolase activity:

Catalysis of the hydrolysis of various bonds

e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc.

Hydrolase is the systematic name for any enzyme of EC class 3.



The name Domain containing 2 illustrate it has 2 domains

Sequence and Secondary Structure /Link

Sequence and secondary structure.png

From the above diagram, we see 2 domains color in blue and purple showed separately.

Type: polypeptide(L)

Length: 259 residues

Secondary Structure: 44% helical (14 helices; 123 residues) 17% beta sheet (12 strands; 48 residues)

2HO4Aa: pdp domain 2HO4Aa (in purple)

2HO4Ab: pdp domain 2HO4Ab (in blue)


But this does not conclude all it's function

So where's the evidence from?

The evidence was done by Mammalian Orthology Load, which information was derived from Homologene National Center for Biotechnology Information. This polymer was reviewed in 2004 and record with J Number: J:90500.

The Mammalian Orthology Query Results shows the Orthology Evidence were used both Amino acid sequence comparison and NT Nucleotide sequence comparison. With species of human, mouse(laboratory), rat, chimpanzee and dog(domestic) all contain this polymer.

What about it's functional partners

From /STRING uses orthology information from the excellent COG database, we predicted it's functional partners.

From the result of occurrence we discover KIAA0423 annotation, which is still not available (1723 aa) is it best suit predicted Functional Partners. / more information

HDHD2 and predicted functional partner.png

The above result shows using protein sequence of ploymer to compare in difference species and their sequence conservation.

e.g. Pan troglodytes and Homo sapiens are two species with this polymer similiar


How does hydrolase activity?

The HAD (haloacid dehalogenase) superfamily of hydrolases contains enzymes such as L-2-haloacid dehalogenase, epoxide hydrolase and a variety of phosphatases





HDHD2 (259 aa) (Homo sapiens) is highly conservatity to Pan troglodytes, Macaca mulatta, Rattus norvegicus, Mus musculus species.

Predicted Functional Partners: KIAA0423 annotation not available (1723 aa)
