Glutathione S-transferases (GSTs) comprise a diverse superfamily of enzymes found in organisms from all kingdoms of life. GSTs are involved in diverse processes, notably small-molecule biosynthesis or detoxification, and are frequently also used in protein engineering studies or as biotechnology tools. Here, we report the high-resolution X-ray structure of Atu5508 from the pathogenic soil bacterium Agrobacterium tumefaciens (atGST1). Through use of comparative sequence and structural analysis of the GST superfamily, we identified local sequence and structural signatures, which allowed us to distinguish between different GST classes. This approach enables GST classification based on structure, without requiring additional biochemical or immunological data. Consequently, analysis of the atGST1 crystal structure suggests a new GST class, distinct from previously characterized GSTs, which would make it an attractive target for further biochemical studies.

Figure 2.
Figure 2. Dimerization of atGST1: (A) Stereo diagram of the hydrophobic key (Phe56) and lock (Leu97, lle101, Ala105, Trp136, lle139, Phe140, and Thr143) motif. The atGST1 lock-and-key motif is shown superimposed on the corresponding regions from -GST (6gsv). The ligand in the active site of 6gsv, (9S,10S)-9-(S-glutathionyl)-10-hydroxy-9,10-dihydrophenanthrene (GPS) is shown in ball-and-stick. The atGST1 dimer is colored in forest green and blue, while the -GST dimer is colored in grey and pink. (B) Stereo diagram of the biologically relevant dimer of atGST1, color-coded from N-terminus (blue) to C-terminus (red).
Figure 4.
Figure 4. GST class-specific motifs shown in the context of a multiple-structure alignment of representative GSTs. Stereo representations of the C[ ]trace of atGST1 is colored red and all other GSTs are shown in grey. The seven motifs that define the various GST classes are labeled: (I) N catalytic tyrosine (ball-and-stick, orange), (II) mu loop (cyan), (III) hydrophobic Key (ball-and-stick, magenta), (IV) SNAIL/TRAIL motif (grey helix), (V) catalytic Asp that binds glutathione across the dimer interface (ball-and-stick, red), (VI) catalytic histidine (ball-and-stick, blue), and (VII) C' extension (C[ ]trace, magenta). For clarity, the corresponding motifs, when present in atGST1, are shown in forest green and arrows indicate the general positions of these motifs.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
