Abstract

This entry represents MECDP (2-C-methyl-D-erythritol 2,4-cyclodiphosphate) synthetase, an enzyme in the non-mevalonate pathway of isoprenoid synthesis, isoprenoids being essential in all organisms. Isoprenoids can also be synthesized through the mevalonate pathway. The non-mevolante route is used by many bacteria and human pathogens, including Mycobacterium tuberculosis and Plasmodium falciparum. This route appears to involve seven enzymes. MECDP synthetase catalyses the intramolecular attack by a phosphate group on a diphosphate, with cytidine monophosphate (CMP) acting as the leaving group to give the cyclic diphosphate product MEDCP. The enzyme is a trimer with three active sites shared between adjacent copies of the protein. The enzyme also has two metal binding sites, the metals playing key roles in catalysis[PubMed12499535].

A number of proteins from eukaryotes and prokaryotes share this common N-terminal signature and appear to be involved in terpenoid biosynthesis. The ygbB protein is a putative enzyme of this type [PubMed10694574].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 5 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a IpsF-like domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 5 hidden Markov models representing the IpsF-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
