Aspartokinase II; Similar to PID:928811 SP:P53553 percent identity: 67.00; identified by sequence similarity; putative.

5-methyltetrahydropteroyltriglutamate-- homocysteine methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.

Hypothetical protein; Identified by sequence similarity; putative.

Homoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine. Utilizes a ping-pong kinetic mechanism in which the acetyl group of acetyl-CoA is initially transferred to the enzyme to form an acetyl-enzyme intermediate before subsequent transfer to homoserine to form the final product, O-acetylhomoserine. Has weak activity with succinyl-CoA as the acyl donor. Belongs to the MetA family.

Cystathionine gamma-synthase; Catalyzes the racemization of L-alanine to D-alanine, and of L-glutamate to D-glutamate. The activity is low, but likely physiological since T.maritima lacks canonical alr and murI genes, while D-alanine and D-glutamate are essential components of peptidoglycan. Also displays a more efficient cystathionine beta-lyase (CBL) activity, cleaving cystathionine to homocysteine and pyruvate; however, this reaction seems not to be physiologically relevant since T.maritima possesses an O-acetyl-homoserine thiolase (MetY) that bypasses the need of CBL for methionine [...]

Thiophene oxidation protein ThdF-related GTPase; Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA- cmnm(5)s(2)U34; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. TrmE GTPase family.

S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.

Formate--tetrahydrofolate ligase; Similar to SP:P13419 PID:144810 percent identity: 74.14; identified by sequence similarity; putative; Belongs to the formate--tetrahydrofolate ligase family.

methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
