FIG. 1.

Putative gene cluster in Halobacterium sp. strain NRC-1 indicating putative btuF (Vng1369G), btuC (Vng1370G), and btuD (Vng1371Gm) genes and plasmid constructions. (A) The reported ORF designation and original gene annotation are shown above each gene. Proposed functions are shown below each gene. The reported length (base pairs) of each gene is indicated. Arrows indicate directions of transcription. (B) Brackets connected by solid lines indicate the regions of DNA that were included in the indicated plasmids (pVNG1370-2, pVNG1370-4, pHsBTUC5, pHsBTUD1, pHsBTUF5, and pHsBTUF6). Dashed lines indicate regions that were not included in the plasmids. DNA restriction enzyme sites used for cloning are indicated below the brackets.
