Histidine--tRNA ligase; tRNA synthetases, class-II (G, H, P and S):Anticodon binding domain:Histidyl-tRNA synthetase, class IIa:Aminoacyl-transfer RN.

Alanyl-tRNA synthetase, class IIc:Phosphoesterase, DHHA1:Alanyl-transfer RNA synthetase; Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.

Phenylalanine--tRNA ligase alpha subunit; Beta and gamma crystallin:Phenylalanyl-tRNA synthetase, class IIc:Aminoacyl tRNA synthetase, class II, N-terminal:Phenylalany..; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily.

GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.

H+-transporting two-sector ATPase, delta (OSCP) subunit; F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation; Belongs to the ATPase delta chain family.

Isoleucine--tRNA ligase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile).

Biotin carboxyl carrier protein of acetyl-CoA carboxylase; This protein is a component of the acetyl coenzyme A carboxylase complex; first, biotin carboxylase catalyzes the carboxylation of the carrier protein and then the transcarboxylase transfers the carboxyl group to form malonyl-CoA.

Valine--tRNA ligase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.

Ribosomal protein S7:Ribosomal protein S7, bacterial and organelle form; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, probably blocks exit of the E-site tRNA; Belongs to the universal ribosomal protein uS7 family.
