There have been identified two isoforms, A and G (MSA and MSG, respectively) that differ in size and is attributed to an inserted alpha/beta domain in MSG that may have regulatory function [1,2]. In malate synthases, the TIM beta/alpha-barrel fold and the C-terminal domain are well conserved and the cleft between them forms the active site [1,2,3,4]. MSA and MSG consist of an N-terminal alpha-helical clasp domain, a central TIM barrel domain and a C-terminal helical plug domain. This is the TIM barrel domain of malate synthases.

In malate synthases, the TIM beta/alpha-barrel fold and the C-terminal helical domain are well conserved and the cleft between them forms the active site [1,2,3,4]. This entry represents the C-terminal domain which consists of a five-helix 'plug' connected to the barrel by an extended loop and caps the active site.

They consist of an N-terminal alpha-helical claps, a central TIM barrel and a C-terminal alpha-helical plug. This entry represents the N-terminal clasp that wraps around one side of the TIM barrel and buttressed it [1,2,3,4].
