This is the N-terminal domain found in o-succinylbenzoate synthase (OSBS) enzymes (EC:4.2.1.113). Like other members of the enolase superfamily, OSBS enzymes are composed of a C-terminal catalytic (beta/alpha)7beta-barrel domain Pfam:PF00113 and an N-terminal capping domain with an alpha+beta fold that is found in the enolase superfamily [1]. This domain is different from other enolase super family N-terminal domains such as Pfam:PF03952. This actino-bacterial N-terminal domain lacks the prototypical first two helices of the enolase capping domains. Structural analysis of T. fusca OSBS reveals that this is compensated for with an extra helix appended to the C-terminus [2].	Domain
A, B	PF13378	Enolase C-terminal domain-like (MR_MLE_C)	Enolase C-terminal domain-like	This domain appears at the C-terminus of many of the proteins that carry the MR_MLE_N Pfam:PF02746 domain. EC:4.2.1.40.	Domain
