TABLE 3.

The extracellular proteases of strain 1A02591 predicted by genome sequencing and gene annotation.

Gene ID	Family	Protease	Predicted functions
orf00069	M4	Thermostable neutral proteinase	Degrades extracellular proteins and peptides for bacterial nutrition; thermolysin-like protease
orf00545	S55	SpoIVB peptidase	Essential for the proper development of spores
orf00831	C40	Peptidase P60	Responsible for the degradation of bacterial cell wall components
orf01043 orf03925	S11	D-alanyl-D-alanine carboxypeptidase	Synthesis of bacterial cell walls, cleaving the D-Ala-D-Ala crosslinks in the cell wall peptidoglycans
orf01198	A36	Sigma-E processing peptidase SpoIIGA	Involved in sporulation
orf02124	S1	Peptidase S1	Heat shock protein that combines refolding and proteolytic activities
orf02670	M23	M23 family peptidase	Lyses cell walls of other bacteria, either as a defensive or feeding mechanism
orf03156	S8	Peptidase S8	Some function at extreme temperatures, and others at high or low pH values
orf03370	S8	Serine protease	Involved in nutrition
