Summary: Phenazine biosynthesis-like protein
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
Phenazine biosynthesis-like protein Provide feedback
PhzC/PhzF is involved in dimerisation of two 2,3-dihydro-3-oxo-anthranilic acid molecules to create PCA by P. fluorescens . This family also contains P28176 though there is no significant sequence similarity to PF00303 members. This family appears to be distantly related to PF01678 including containing a weak internal duplication. However members of this family do not contain the conserved cysteines that are hypothesised to be active site residues (Bateman A pers obs).

InterPro entry IPR003719
This entry represents the PhzF family, which includes PhzF and uncharacterised isomerases. PhzF is part of the seven-gene operon phzABCDEFG, responsible for the synthesis of phenazine-1-carboxylic acid (PCA) in Pseudomonas species. PhzF is a trans-2,3-dihydro-3-hydroxyanthranilate isomerase that catalyses the condensation of two molecules of trans-2,3-dihydro-3-hydroxyanthranilic acid (DHHA) into the phenazine ring system. The final product is not yet known [PUBMED:15449932, PUBMED:15545603].

This superfamily includes DAP epimerase and proline racemase as well as the PrpF protein. It has been suggested that this fold may have evolved from the HotDog fold .
The clan contains the following 4 members:DAP_epimerase PhzC-PhzF Pro_racemase PrpF
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

There is 1 interaction for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the PhzC-PhzF domain has been found. There are 24 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
