Chain A,B,C,D (ALR1_ECOLI | P0A6B4)

molecular function
	GO:0008784	alanine racemase activity	Catalysis of the reaction: L-alanine = D-alanine.
	GO:0003824	catalytic activity	Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
	GO:0016853	isomerase activity	Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
	GO:0030170	pyridoxal phosphate binding	Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6.
biological process
	GO:0030632	D-alanine biosynthetic process	The chemical reactions and pathways resulting in the formation of D-alanine, the D-enantiomer of the amino acid alanine, i.e (2R)-2-aminopropanoic acid.
	GO:0006522	alanine metabolic process	The chemical reactions and pathways involving alanine, 2-aminopropanoic acid.
	GO:0071555	cell wall organization	A process that results in the assembly, arrangement of constituent parts, or disassembly of the cell wall, the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis.
	GO:0009252	peptidoglycan biosynthetic process	The chemical reactions and pathways resulting in the formation of peptidoglycans, any of a class of glycoconjugates found in bacterial cell walls.
	GO:0008360	regulation of cell shape	Any process that modulates the surface configuration of a cell.
