Asymmetric/Biological Unit(hide GO term definitions)

Chain A (MSHD_MYCTU | P9WJM7)

molecular function
	GO:0008080	N-acetyltransferase activity	Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
	GO:0035447	mycothiol synthase activity	Catalysis of the reaction: 1-D-myo-inosityl-2-L-cysteinylamido-2-deoxy-alpha-D-glucopyranoside + acetyl-CoA = mycothiol + coenzyme A + H+. Mycothiol is also known as AcCys-GlcN-Ins and 1-D-myo-inosityl-2-L-cysteinylamido-2-deoxy-alpha-D-glucopyranoside as Cys-GlcN-Ins or desacetylmycothiol.
	GO:0004596	peptide alpha-N-acetyltransferase activity	Catalysis of the reaction: acetyl-CoA + peptide = CoA + N-alpha-acetylpeptide. This reaction is the acetylation of the N-terminal amino acid residue of a peptide or protein.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
	GO:0016746	transferase activity, transferring acyl groups	Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor).
	GO:0016747	transferase activity, transferring acyl groups other than amino-acyl groups	Catalysis of the transfer of an acyl group, other than amino-acyl, from one compound (donor) to another (acceptor).
biological process
	GO:0006474	N-terminal protein amino acid acetylation	The acetylation of the N-terminal amino acid of proteins.
	GO:0044119	growth of symbiont in host cell	The increase in size or mass of symbiont, occurring in its host's cell. The host is defined as the larger of the organisms involved in a symbiotic interaction.
	GO:0010125	mycothiol biosynthetic process	The chemical reactions and pathways resulting in the formation of mycothiol, which consists of N-acetyl-L-cysteine linked to a pseudodisaccharide, D-glucosamine and myo-inositol. Mycothiol is produced in actinomycetes like mycobacteria and serves similar functions to glutathione.
	GO:0006950	response to stress	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation).
cellular component
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
	GO:0031248	protein acetyltransferase complex	A complex that catalyzes the transfer of an acetyl group to a protein acceptor molecule.

	GO:0010125	mycothiol biosynthetic process	The chemical reactions and pathways resulting in the formation of mycothiol, which consists of N-acetyl-L-cysteine linked to a pseudodisaccharide, D-glucosamine and myo-inositol. Mycothiol is produced in actinomycetes like mycobacteria and serves similar functions to glutathione.
