1-317 | 0e+00 | |||||
hopanoid biosynthesis associated radical SAM protein HpnH; The sequences represented by this model are members of the radical SAM superfamily of enzymes (pfam04055). These enzymes utilize an iron-sulfur redox cluster and S-adenosylmethionine to carry out diverse radical mediated reactions. The members of this clade are frequently found in the same locus as squalene-hopene cyclase (SHC, TIGR01507) and other genes associated with the biosynthesis of hopanoid natural products. The linkage between SHC and this radical SAM enzyme is strong; one is nearly always observed in the same genome where the other is found. A hopanoid biosynthesis locus was described in Zymomonas mobilis consisting of the genes HpnA-E and SHC (HpnF). Continuing past SHC are found a phosphorylase enzyme (ZMO0873, i.e. HpnG, TIGR03468) and this radical SAM enzyme (ZMO0874) which we name here HpnH. Granted, in Z. mobilis, HpnH is in a convergent orientation with respect to HpnA-G, but one gene beyond HpnH and running in the same convergent direction is IspH (ZM0875, 4-hydroxy-3-methylbut-2-enyl diphosphate reductase), an essential enzyme of IPP biosynthesis and therefore essential for the biosynthesis of hopanoids. One of the well-described hopanoid intermediates is bacteriohopanetetrol. In the conversion from hopene several reactions must occur in the side chain for which a radical mechanism might be reasonable. These include the four (presumably anaerobic) hydroxylations and a methyl shift. The actual alignment was detected with superfamily member TIGR03470: Pssm-ID: 274595 [Multi-domain] Cd Length: 318 Bit Score: 577.84 E-value: 0e+00

Radical SAM superfamily. Enzymes of this family generate radicals by combining a 4Fe-4S cluster and S-adenosylmethionine (SAM) in close proximity. They are characterized by a conserved CxxxCxxC motif, which coordinates the conserved iron-sulfur cluster. Mechanistically, they share the transfer of a single electron from the iron-sulfur cluster to SAM, which leads to its reductive cleavage to methionine and a 5'-deoxyadenosyl radical, which, in turn, abstracts a hydrogen from the appropriately positioned carbon atom. Depending on the enzyme, SAM is consumed during this process or it is restored and reused. Radical SAM enzymes catalyze steps in metabolism, DNA repair, the biosynthesis of vitamins and coenzymes, and the biosynthesis of many antibiotics. Examples are biotin synthase (BioB), lipoyl synthase (LipA), pyruvate formate-lyase (PFL), coproporphyrinogen oxidase (HemN), lysine 2,3-aminomutase (LAM), anaerobic ribonucleotide reductase (ARR), and MoaA, an enzyme of the biosynthesis of molybdopterin.

SynChlorMet cassette radical SAM/SPASM protein ScmE; A biosynthesis cassette found in Syntrophobacter fumaroxidans MPOB, Chlorobium limicola DSM 245, Methanocella paludicola SANAE, and delta proteobacterium NaphS2 contains two PqqE-like radical SAM/SPASM domain proteins, a PqqD homolog, and a conserved hypothetical protein. These components suggest modification of a ribosomally produced peptide precursor, but the precursor has not been identified. Of the two PqqE homologs of the cassette, this family is the closer in sequence. Pssm-ID: 211973 [Multi-domain] Cd Length: 358 Bit Score: 41.77 E-value: 4.85e-04
