FIG. 1.

Partial sequence analysis of the cytochrome c maturation operon of P. putida GB-1 compared with that of P. fluorescens ATCC 17400 (27). The (partial) genes are designated ccmA through ccmI, as recently proposed by Page et al. (33). Restriction sites are indicated by arrows (E, EcoRI; P, PstI; S, SmaI; Sa, SalI). Sites marked by an asterisk are part of the multiple cloning region of the complementing cosmid pPLH38. The sites of Tn5 insertions in GB-1-003 and GB-1-004 are indicated by open triangles. Plasmids pCYT01 through pCYT04 were obtained by PstI deletion of pPLH38. The accession numbers for sequences are as follows: ccmA through ccmC, U85716; ccmF, U85717; and ccmH, U85718. b, bases.
