Overview

The original HydG (BBa_K1998010) (https://parts.igem.org/Part:BBa_K1998010) was not submitted in 2016 as the DNA sequence had a mutation present. HydG was re-synthesised by Macquarie iGEM 2017. HydG is a radical S-adenosyl methionine (SAM) enzyme which functions as part of the [FeFe] hydrogenase maturation enzyme complex. All organisms with [FeFe] hydrogenase contain homologues of this gene (Mulder et al., 2010).

Part Verification

Fig 1. Agarose gel (1%) electrophoresis of single (EcoRI) and double (Eco-RI with PstI) digests of parts.

Left: Lane 1 contains a 1kb ladder. Lanes 2 and 3 show single (~10,700bp) and double (~8700bp with ~2000bp) digests respectively of the composite Hydrogen Gas Producing Gene Cluster plasmid (HGPGC). Lanes 4 and 5 show single (~7400bp) and double (faint ~5400bp with ~2000bp) digests of hydEFG. Lanes 6 and 7 show single (~5400bp) and double digests (~3400bp with ~2000bp) of fer/hyd1.

Right: Lane 1 contains a 1kb ladder. Lanes 2 and 3 show double digests (~1900bp with ~2000bp) and single digest (~3900bp) of hydG.
