TABLE 2.

Similarities of the N-terminal amino acid sequences of purified benzoate-CoA ligase from D. multivorans and other characterized benzoate CoA ligases

Organism	N-terminal sequencea	Molecu- lar mass (kDa)	Accession no.	Reference
D. multivorans	1GFEIKLPEHFNAAD14	59		This work
T. aromaticab	13PPAIKIPERYNAAD26	57c	AAN32621	41
A. evansii (aerobic)b	13PPTITLPRQYNAAD26	58c	AAN39371	19
A. evansii (anaerobic)b	13PPRITIPREYNAAD26	57c	CAD21640

^aIdentical amino acids are shown in boldface; similar amino acids are shown in italics.

^bT. aromatica uses a single benzoate CoA ligase for both the aerobic and anaerobic aromatic metabolisms, whereas A. evansii expresses two different enzymes (19, 41).

^cDeduced from the gene sequence.
