FIG. 1.

Genomic region of ndh1 and ack2.ndh1 (NADH dehydrogenase) forms part of an operon-like structure with a transcription factor (c) and an integral membrane protein (d) that neighbors the acetate kinase gene (ack2). ack2 itself is flanked by another integral membrane protein (a) and a putative acetyl transferase (b).
