A weaker element located between -230 and -170 defined the minimum 5' region required for detectable promoter activity. Reactivation of inactive promoters with deletion endpoints between -230 and the transcription initiation site was obtained employing the constitutive cauliflower mosaic virus (CaMV) 35S enhancer. The position of cis regulatory element(s) required for nodule-specific expression was defined to 37 bp between -139 and -102.

This region contains sequences conserved in other leghaemoglobin and nodulin genes. No indispensable control elements were found on the lbc(3) 3' flanking region.
