Signal peptide – transient ‘zip code’ of premature protein which facilitates the secretion of protein in Bacillus subtilis.

YbdN – Signal peptide of protein YbdN in Bacillus subtilis.

ybdN – Gene that codes for YbdN.

YdjM – Signal peptide from protein YdjM in Bacillus subtilis.

ydjM – Gene that codes for YdjM.

BMP2 – Bone morphogenetic protein 2.

LytC – B. subtilis inherent cell-wall associated hydrolase mediating cell-wall turnover.
