Malate synthase (MS) catalyses the aldol condensation of glyoxylate with acetyl-CoA to form malate as part of the second step of the glyoxylate bypass and an alternative to the tricarboxylic acid cycle in bacteria, fungi and plants. 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.
