Proteolipid is known to initiate calcification in vitro. Apoprotein and phospholipid components of proteolipid from five of 14 calcifiable S. mutans specimens were characterized. The apoproteins contained 16 amino acids with calculated percent polarities ranging from 32.0 to 45.2. The acidic phospholipids were cardiolipin, mono- and diphosphoinositides, and phosphatidylserine. Neutral lipids, phosphatidylethanolamine and phosphatidylcholine, were also found. The latter were the most abundant in all isolates. Appropriate hydrophobic proteins and acidic phospholipids in the proteolipids accounted for S. mutans calcifiability.
已知蛋白脂质可在体外引发钙化。对14株可钙化变形链球菌标本中的5株的蛋白脂质的载脂蛋白和磷脂成分进行了表征。这些载脂蛋白含有16种氨基酸，计算出的极性百分比范围为32.0%至45.2%。酸性磷脂为心磷脂、单磷酸和二磷酸肌醇以及磷脂酰丝氨酸。还发现了中性脂质，即磷脂酰乙醇胺和磷脂酰胆碱。后者在所有分离株中最为丰富。蛋白脂质中适当的疏水蛋白和酸性磷脂导致了变形链球菌的钙化能力。
